Time Stamp Offset end playback TDMS
I am having a problem with a PDM file playback and display a graphic in the shape of wave in LabVIEW. My table of waveform display always the time with a negative offset of 18 000 samples.
Who make it simple, let's say I'm sampling to 1000 samples per second, and I connect my PDM data. When I read that PDM and visualize my graphic waveform data, the chart display data read from DDHN 18 seconds earlier that the registered wf_start_time, set a deadline for the PDM. If my wf_start_time is 08:00:20.000 AM 12/02/2014, then my waveform displays a start time of 08:00:02.000 AM 12/02/2014. Even if I taste 4000 samples per second, my start time is disabled starting 4.5 seconds earlier.
I put my Xscale.offset = wf_start_time it reads properly, but the start time on the waveform table is always false.
Because I'm dealing with large TDMS files (500 MB +), I sometimes decimate the data to view it due to problems of memory. Here, this problem occurs again. If I decimate the data to display only 1 out of every 10 data points, this offset is more changing by a factor of 10 x. ranging from 18 seconds to 180 seconds.
Is this some sort of gap of stamp UTC/system clock time or something else?
Looks like that I thought about it. I copy - paste a previous screw waveform graph on a whim, I created a graph of waveform from scratch, and the lag problem has been eliminated. It must have been an option or shift created in there that I couldn't see or modify. But it's good now.

Hi all just make me this error with KernelBase.dll, what happens to my end of the application, is that I am using .NET Framework to determine if network connectivity is available, to raise an event from a dll underlying to notify the application when network connectivity is established, or network connectivity is not available. Nothing really special here just using standard stuff of .net framework here. Have seen similar incidents withKERNELBASE.dll reported, but nobody of really give any info on which exception 0xe0434f4d is a code. Knowing what would be the execption, would allow me to find a quick solution to the problem. BizTalk seems to have a similar problem with KERNELBASE.dll.
Additional information that may help is that I am under the .NET application on a Windows 7 computer less than 100 MB of storage space, well below the recommended minimum of 300 MB, but test the .NET to test application it is now. This should work if Windows 7 does not work.

TDMS of MDF time stamp conversion error / storage date time change
I fought it for a while, I thought I'd throw it out there...
Let's say I have a file TDMS which has a channel of labview time stamp and thermocouple 2.
I load in DIADEM, I get this:
Perfect! But now let's say I want to save the PDM as a MDF file so I can see him in Vector sofa. I right click and save as MDF, perfect. I started couch and get this:
The year 2121, yes I take data on a star boat! It seems to be taking the stamp of date/time storage TDMS as starting point and adding the TC_Timestamp channel.
If I change the channel of TC_Timestamp to 1, 2, 3, 4, 5, 6, 7 etc... and save as MDF, I get this:
Very close, 2012! But what I really want is what to show of the time, it was recorded what would be the 10/09/2012.
The problem is whenever I do like recording, date storage time is updated right now, then the MDF plugin seems to use it as a starting point.
is it possible to stop this update in TIARA?
Thank you
Ben
Hi Ben,
You got it right that the MDF use written the time of storage to start MDF that is updated by DIAdem when writing time. We are working on this and will return to you, if there is no progress.
To work around the problem, you can try convert TDMS MDF in LabVIEW storage vis.
Something like the following, you can write your start time of measurement to the MDF file.
Hope this helps,

Time-stamped comments adding in a DDHN file during logging
I'm trying to find the best way to add comments in a DDHN file during logging. I know that the fragmentation occurs when the properties are written for TDMS logging. Should I write comments in the level in the logging file (maybe a case of Structure fires when a new comment occurs) or is there another way to incorporate comments into a DDHN file during logging that I'm missing? Any help would be appreciated.
Nathan, do you really care about fragmentation? If this isn't the case, you could do it just like that. If you really care fragmantation, you could write Time-Stamped comments in a separate file, PDM, or any, Time-Stamped cache and write cached put comments in the PDM file after cutting.

How to add a time stamp to a PDM file
I need to add a time stamp to my PDM file. Currently, I take an array of doubles, their conversion to a type of dynamic data, then send to tdms_write. I have to add a timestamp, but I can't find a way to do it. I also tried holding the timestamp, converting it into a doube, U64 and I64 and adding that to my table before the dynamic data conversion type, but when I lose precision. I need to have at least millisecond resolution. I know that I lose accuracy because the timestamp is two 64-bit values. top 64-bit are set to seconds since the epoch and lower 64 bit are fractions of a second. I would even send these two numbers divided in my happy tdms file and conversion at a later date, but can't seem to do it again. Any help would be appreciated.
The natural way would be using a waveform.
You can add your timestamp as two U64 (using cast to array U64) as properties of the channels as data t0.

file lvm recorded with time stamp graphic display
Hello
I have headaches display my data with correct timestamp. There are so many methods to save the data. Here, I decided to save it in a text delimited as lvm. a screenshot of my vi segment is attached. I want to use this way rather than other methods is the flexibility it offers. I'll be able to add more data to store that I develop the vi. (So I'm storing data of the DAQ assistant and my calculated values.) I've attached a screenshot of the file I also read.
I would use another vi to open this file and it draw a chart/graph to show a trend of the acquired data. Can someone pls Advisor mid on which is a better way for mi to do?
Thank you very much!

Hi Malou,
Sorry for the late reply, I was rushing to complete my project, has not been able to answer.
Yes, I managed to solve it. In any case, I've used this high rate in the acquisition of data wizard is to allow the acquisition of continuous mode & use a software filter instead of filter material. However writes to the folder this way - write string in .lvm, max is 10 samples/s unless I have use tdm (I'll then everything in the newspaper).
I was not able to display the correct timestamp was due to the fact that I have does not add to the timestamp of the start time for the timestamp in waveform display. I won't be able to go down to my lab, & my machine have no LabVIEW, so what I do is to extract some parts of my report to share.
For the part that I used to display the graph (can be seen on the attachment), I deleted the 1st column, which is the time stamp (for display of the spreadsheet), but extract the 1st element - convert timestamp DBL it when I start recording in the DAQ vi (written with the header).
This excerpt (which could be considered as a group of numbers in the file lvm) and converted to the type timestamp and wired for generating waveform block, providing the start time of the wave.
Then I replace the use of the chart with graphic, graphic is suitable for data acquired and graphic tracing is better for the time of execution of the data display. now it seems to work fine for me, except for the load time may take some time for larger files.
Thank you for your participation in this thread!
See you soon!

BEFORE the UPDATE of relaxation with time stamp does not work as expected
We have a scenario where I check update operations on a table.
I created a before update TRIGGER, so that every time he goes an update on the main table statement, one before the image of the lines is captured in the table of audit with timestamp.
Since it is before updating, ideally the audit table timestamp (TRG_INS_TMST) should be less main table timestamp (IBMSNAP_LOGMARKER) VALUE, I mean TRIGGER should happen before the update.
(I could understand in a way that the UPDATE statement is formulated with SYSTIMESTAMP earlier before the TRIGGER is evaluated and so UPDATE is to have a time stamp prior to TRIGGER, but this isn't what we wanted. We want PRIOR update)
'Table' IBM_SNAPOPERATION IBM_SNAPLOGMARKER ---- ----------------- ------------------------------- T1 U 13-OCT-15 03.07.01.775236 AM <<---------- This is the main table, This should have the latest timestamp T2 I 13-OCT-15 03.07.01.775953 AM
Here is my test case.
DELETE FROM TEST_TRIGGER_1; DELETE FROM TEST_TRIGGER_2; SELECT 'T1', ibm_snapoperation, ibm_snaplogmarker FROM TEST_TRIGGER_1 UNION SELECT 'T2', ibm_snapoperation, TRG_INS_TMST FROM TEST_TRIGGER_2; INSERT INTO TEST_TRIGGER_1 (ID,ibm_snapoperation, ibm_snaplogmarker) VALUES (1, 'I', SYSTIMESTAMP); COMMIT; SELECT 'T1', ibm_snapoperation, ibm_snaplogmarker FROM TEST_TRIGGER_1 UNION SELECT 'T2', ibm_snapoperation, TRG_INS_TMST FROM TEST_TRIGGER_2; UPDATE TEST_TRIGGER_1 SET IBM_SNAPOPERATION = 'U', ibm_snaplogmarker = SYSTIMESTAMP; COMMIT; SELECT 'T1', ibm_snapoperation, ibm_snaplogmarker FROM TEST_TRIGGER_1 UNION SELECT 'T2', ibm_snapoperation, TRG_INS_TMST FROM TEST_TRIGGER_2;
Def trigger:
CREATE OR REPLACE TRIGGER etl_dbo.TEST_TRIGGER_1_TRG BEFORE UPDATE OF IBM_SNAPOPERATION ON TEST_TRIGGER_1 REFERENCING OLD AS OLD NEW AS NEW FOR EACH ROW WHEN ( NEW.IBM_SNAPOPERATION= 'U' ) DECLARE V_SQLCODE VARCHAR2(3000); --PRAGMA AUTONOMOUS_TRANSACTION; BEGIN INSERT INTO etl_dbo.TEST_TRIGGER_2 (ID, IBM_SNAPOPERATION, IBM_SNAPLOGMARKER, TRG_INS_TMST ) VALUES (:OLD.ID,:OLD.IBM_SNAPOPERATION,:OLD.IBM_SNAPLOGMARKER,SYSTIMESTAMP) ; --COMMIT; END; /
Output is something like this
1 row deleted. 1 row deleted. no rows selected. 1 row created. Commit complete. 'T1' IBM_SNAPOPERATION IBM_SNAPLOGMARKER ---- ----------------- ------------------------------- T1 I 13-OCT-15 03.07.00.927546 AM 1 row selected. 1 row updated. Commit complete. 'T1' IBM_SNAPOPERATION IBM_SNAPLOGMARKER ---- ----------------- ------------------------------- T1 U 13-OCT-15 03.07.01.775236 AM <<---------- This is the main table, This should have the latest timestamp T2 I 13-OCT-15 03.07.01.775953 AM 2 rows selected.
But for some reason, even after the creation of the 'AFTER' trigger for update, it works as expected. Sense - the main table is not having the last timestamp given
It's OKAY - I told you in my reply earlier. Reread my answer.
could understand somehow that the UPDATE statement is made with earlier
SYSTIMESTAMP until the TRIGGER is assessed and updated so is to have
time stamp prior to the trigger, but this isn't what we wanted. We want to
BEFORE the update)
As I told you before that your UPDATE statement occurs BEFORE the trigger is activated.
Despite what the other speakers have said, it makes NO DIFFERENCE if you use a BEFORE UPDATE or an AFTER UPDATE trigger. Your UPDATE statement runs ALWAYS BEFORE the trigger.
HE has TO - it's your update processing statement that causes the trigger to fire.
Your update statement includes SYSTIMESTAMP. If during the processing of your return to update the value of SYSTIMESTAMP "at this exact time" is captured.
Then your trigger is activated and starts to run. ANY reference to SYSTIMESTAMP that you use in your trigger cannot be earlier than the value of until the trigger was executed. It's IMPOSSIBLE.
The trigger can use the SAME value by referencing: NEW and the column name you store the value. Or the trigger can get its own value that your code is doing.
But the SYSTIMESTAMP value in the trigger will NEVER earlier than the value in your query.
And none of these values can actually be used to tell when the changes are really ENGAGED since the trigger does not work and CAN NOT, to know when, or if, a validation occurs.
Reread my first answer - he explains all this.

How can I set a time stamp for the setCreationDate(Date value)?
Hi all
My underlying database column has a DATE data type that needs of the data and the time stamp. When you use the following code to set a date for setCreationDate(Date value) the date is set, but there is no timestamp.
Here is the code:
protected void create (AttributeList attributeList) {}
Super.Create (AttributeList);
Begin
Date currentDate = new Date();
DATE creationDate = currentDate.getCurrentDate ();
setCreationDate ((Date) creationDate);
End
}
Can't wait to hear.

overloading a DATE with time STAMP function to avoid the "too many declarations.
Originally, I had just the a function with the arguments of VARCHAR2. It worked not correctly because when the dates were gone, the automatic conversion into VARCHAR2 lowered the timestamp. So, I added a 2nd function with the arguments to DATE. Then I started to get "too many declarations of is_same exist" error during the passage of time stamps. This made no sense to me, so, although documentation Oracle says you can't do this, I created a 3rd version of the function, to manage the TIMESTAMPS explicitly. Surprisingly, it works fine. But then I noticed that he did not work with TIMESTAMP with time zones. Therefore, the fourth version of the function. Docs of the Oracle say that if your arguments are of the same family, you can't create an overloaded function, but in the example above shows, it's very bad.CREATE OR REPLACE PACKAGE util AS FUNCTION yn (bool IN BOOLEAN) RETURN CHAR; FUNCTION is_same(a varchar2, b varchar2) RETURN BOOLEAN; FUNCTION is_same(a date, b date) RETURN BOOLEAN; /* Oracle's documentation says that you cannot overload subprograms * that have the same type family for the arguments. But, * apparently timestamp and date are in different type families, * even though Oracle's documentation says they are in the same one. * If we don't create a specific overloaded function for timestamp, * and for timestamp with time zone, we get "too many declarations * of is_same match" when we try to call is_same for timestamps. */ FUNCTION is_same(a timestamp, b timestamp) RETURN BOOLEAN; FUNCTION is_same(a timestamp with time zone, b timestamp with time zone) RETURN BOOLEAN; /* These two do indeed cause problems, although there are no errors when we compile the package.

Finally, just for grins, I created the functions of number two, one number, the other with REAL and even these are allowed - they are compiled. But then, at runtime, it fails. I'm really confused.
Here's the apparently erroneous Oracle documentation on this subject: http://docs.oracle.com/cd/B12037_01/appdev.101/b10807/08_subs.htm (see overload subprogram names) and here are the different types and their families: http://docs.oracle.com/cd/E11882_01/appdev.112/e17126/predefined.htm.

This is because when you pass a TIMESTAMP Oracle cannot determine whether to implicitly convert to VARCHAR2 and use your first function or implicitly convert to DATE and use your second function. Where the "too many declarations" error exist.

I think that the documentation, of the family of 'date', is wrong as you suggest. For WHOLE and REAL, the problem is that those are the ANSI data types and are really the same Oracle data type; they are more like "alias" that different data types.See the doc of SQL language

ANSI SQL/DS and DB2 data typesThe SQL statements that create tables and clusters allows also ANSI data types and products IBM SQL/DS and DB2 data types. Oracle recognizes the ANSI or IBM data type name that differs from the Oracle database data type name. It converts the data type for the equivalent Oracle data type, stores the Oracle data type under the name of the column data type and stores the data in the column in the data type Oracle based on the conversions listed in the following tables.

Strange problem casting between the DATE and time STAMP

Look at the strange data that stamp_copy was after the update.
When run from SQL over, everything is fine. But when I run this code in our application, the same phenomenon occurs. I've even seen a data dating back to the year 11907 (!), giving an exception by selecting from the table.
Someone at - it an idea on how to work around this bug?

There are a few listed in this blog, that may be useful for you.

Hi guys
I have a table and the date in a column value is stored in varchar2 (35)
It is stored to take time up to milliseconds as below
Select transaction_date in the table
12:43:04:651 09/09/2009
now, I want to vatchar2 convert timestamp data type in my table
to keep the data in the sound and start with the exception of the new data according to the timestamp data type
I don't know why the previous developers took varchar instead of timestamp
our production server is in the United States and the data entered through the India and business also
So they used the varchar data type to store the milliseconds
Use a procedure to have time ist
now I can change the timestamp data type without affecting the data
I think that its really need and it is not good to store the date in varchar
the procedure I know to change the data type is as below
1. Create Table smsrec_dup as select Rowid Row_Id, transaction_date sms_rec;
2 update sms_rec Set transaction_date = Null;
3.commit;
4 Alter Table sms_rec change transaction_date timestamp (3);
5 setting a day sms_rec B Set transaction_date = (Select transaction_date of smsrec_dup A where B.Rowid = A.Row_Id);
6.commit;
above to change the data of TIMESTAMP type
NOW, I WANT TO HOW COULD I INSERT TIME IST
CURRENTLY developers use a procedure for STI
AS
CREATE OR REPLACE PROCEDURE current_tstamp (real out varchar2)
AS
var_sign varchar2 (2);
var_zone varchar2 (35);
time TIMESTAMP;
BEGIN
Select substr (systimestamp, 30.1), to_char (systimestamp, 'tzr') in var_sign, double var_zone;
IF var_sign = "+" THEN
IF var_zone = "+ 05:30 ' THEN"
SELECT to_char (systimestamp, ' dd/mm/yyyy hh24:mi:ss:ff3 "") in the double real;
dbms_output.put_line (actual);

I just want to explain about this a bit...
change time zone at the database level is quite a bad idea...
because if you change the time zone then what about all the data that might be present in the same database used by other applications, as appropriate.
I'm not sure, but if dbtimezone is changed so if you have date or timestamp columns with tables so the values inside of get them adjusted to the time zone has changed.first of all understand the diff between...
If you use systimestamp (which is not really a timestamp data type appear perfectly what timestamp with time zone) must always dbtimezone time zone (as obtained from timezone database).
You use localtimestamp (which is a timestamp data type) if the timestamp at the session that you set for him. by default, it will take the client's time zone.
If you use current_timestamp (which is a local timestamp with time zone data type), we have to the time stamp and the time zone at the session that you define for him...
SQL> alter session set time_zone='+05:30' 2 ; Session altered. SQL> select systimestamp,current_timestamp,localtimestamp from dual; SYSTIMESTAMP --------------------------------------------------------------------------- CURRENT_TIMESTAMP --------------------------------------------------------------------------- LOCALTIMESTAMP --------------------------------------------------------------------------- 10-SEP-09 05.15.03.531687 AM -04:00 10-SEP-09 02.45.03.531716 PM +05:30 10-SEP-09 02.45.03.531716 PM SQL> alter session set time_zone='+04:30'; Session altered. SQL> select systimestamp,current_timestamp,localtimestamp from dual; SYSTIMESTAMP --------------------------------------------------------------------------- CURRENT_TIMESTAMP --------------------------------------------------------------------------- LOCALTIMESTAMP --------------------------------------------------------------------------- 10-SEP-09 05.15.39.840319 AM -04:00 10-SEP-09 01.45.39.840350 PM +04:30 10-SEP-09 01.45.39.840350 PM
See above see you systimestamp does not change but current_timestamp and localtimestamp change with session timestamp...
Until this is localtimestamp... speak frankly... it will get the time stamp of the client... If you use a sql developer then it will show the timestamp on your desktop... But in a 3-tier application... I mean applicationlayer-customer data base, the database client is application layer not the end user PC. He will get the time zone of the server application. So using timestamp with local time zone can be waived if you use 2-tier application or desktop.
Here's the real story...
So what I mean is that... This is the application layer send the time zone of the client to the database... If the database when inserting (indirectly, your willingness to insert queries) convert the timestamp to whatever you want...for example...
I am inserting a record into the database table that has a timestamp data type... so... I inserted at 14:56 ISTSQL> insert into test_tz(col1) values(systimestamp); 1 row created. SQL> select col1 from test_tz; COL1 --------------------------------------------------------------------------- 10-SEP-09 05.25.41.497759 AM SQL>
If you see he showed he showed the time server by deleting the part of zone. Since then, you would like to insert in the TSI data then...
SQL> truncate table test_Tz; Table truncated. SQL> insert into test_tz(col1) values(systimestamp at time zone 'Asia/Calcutta'); 1 row created. SQL> select col1 from test_tz; COL1 --------------------------------------------------------------------------- 10-SEP-09 02.59.57.087032 PM
He showed the real time of the insert as IST.
.....................................
If you want to set the level of the session then you must use localtimestamp as you used in your post...But regardless of how you use... you must spend the time zone of the client to the server, I mean 5:30 ' or "Asia/Calcutta" whatever inside your sql queries.

Script Automator for the DATE and TIME stamped record
Hi all
I'm not a scripter, but are in need of a DATE and time-STAMPED folder (or file) I would like to put on my desktop and have updated automatically so that I can use this tool to quickly see if a backup external (or internal) is current. probably I could also use it to quickly find out how /old/ a backup is.
for now, I do this manually if I want to quickly verify that a backup works by creating a "date named folder" on the desktop - such as '-2016 03 26 "."» so I can quickly see if a backup I just ran ran.
I have a lot of backups (internal, external, off site, etc.) and it would be super useful for me to have.
I consider the name of the folder to be customizable (potentially) in case I need to change it, but a good default would be "-YEAR MONTH DAY" so that I could see easily when this backup has been but also I name my files in this way so they can appear in chronological order "."
is anyone able to help me with something like that or suggest another forum for cross-post this?
Thank you
Jon

Acquisition of data high-speed with time stamp
I am acquiring data at a fairly fast speed (5 to 25 kHz) for a few seconds and then writing in a spreadsheet file. Is there a way to set up so that it displays the time stamp for each data point instead of just the data point number?
Of course. Change the type of data returned by DBL 2D to 1 D wave form. This is doen by clicking on the polymorphic selector or right-click and choose 'select the Type '.
