• Not touch event timestamp in milliseconds

  Touch horodateurs event seem to be in microseconds instead of milliseconds.

  The test page prints below touchstart and timestamps touchstart event in the box.

• String to timestamp with milliseconds

  Hi, the image below show me convert the time in a timestamp (and its replacement by a timestamp date different.

  It works great except for the milliseconds. You can see here the milliseconds are defined as "% 2d" and it does not work. If I replace by "2u %" or "% 3u" then the VI will be error (vi attached)

• Timestamp with milliseconds to double

  I need to get my updated timestamp in the form (including to the millisecond) in a double format. I use the channel scan. Any format I use the double issue is always truncated and shows only a reolution of a tenth of a second.

  I need my date/time to the DBL format string because I need to add it to an array of other numbers DBL that is written in a .csv file. So it may not be in the string format (unless theres a way to write both in a .csv file)

  What can I do to get the correct respresentaion?

  Thanks, who takes care of the display on the front panel. However, how to I get it so that such representation is passed out of the function I can write it in my data file?

  The DBL it generates is still only a tenth of a second format.

  Well, which depends entirely on the format string, that you use for when you create your CSV.  You probably want something like "%.6f" for you format.

• How can timestamp in LVM file - I access the ms value?

  Hi all,

  I have a file measurament and when I explain it, I need timestamp with millisecond precision, but I can't read in labview!

• Multiple query processing

  I wonder how BEEP treats multiple queries in a single data model. Get requests executed sequentially or in parallel?

  BEEP data model requests are get executed sequentially.

  To find the sequence order, click on the "Structure" tab if you are on 11g.

  And if you need proof, you can add a column that contains the timestamp with milliseconds on each data model and run the xml data. You will come to know that it's getting executed sequentially.

• See criteria and ADF dates

  Hi all
  I use JDevloper 11.1.2.3.0
  
  I create a view criteria on a calendar page.
  I have an attribute in my DB called start_date timestamp type.
  
  I want the object view where clause to check if the callback is enabled and If start_date is equal currentdate + 1 hour

  SELECT Calendar.DESCRIPTION, 
         Calendar.END_DATE, 
         Calendar.ID, 
         Calendar.PROVIDER, 
         Calendar.REMINDER, 
         Calendar.START_DATE
  FROM CALENDAR Calendar
  WHERE  ( (UPPER(Calendar.REMINDER) = UPPER('ON') ) AND Calendar.START_DATE = ...

  What should be the value? I thought about sysdate + 1/24, but how should I write it?
  
  Thank you very much

  I should be something like this:

  Timestamp oneHourInTheFutre = new Timestamp(System.currentTimeMillis() + (60 * 60 * 1000));
  

  Timestamp in milliseconds, so you add 36000000 milliseconds to get the time + 1 hour.

  Or you can use an expression instead of a variable binding groovy.
  In your case, it should be something like:

  adf.currentDateTime+3600
  

  I'm not sure of the 3600 (stands for 3600 seconds = 1 hour) because you may need to add the time in milliseconds instead of seconds.

• TDMS wf_start_time with milliseconds

  How can I include information millisecond of time of waveform information in my TDMS file?

  Resemble my timestamps: 17/10/2016 08:59:34.000 AM

  Hi sez!

  The DAQmx property do not support to set the properties in the PDM log file.

  

  The only thing you can do is create a file and write the start time property in this file. The DAQmx driver opens this file again and log data in the file.

  

  Basically, you can do it, but I prefer the solution of low level with the TDMS screws indicated in the post before.

• Representation of like SGL timestamp?

  Hi all

  I'm saving the binary data in the course of an application of the RT and want to convert them to ascii. I'm planning to use sgl representation for stored data to reduce the size of the file. However, using means sgl who gets the timestamp 'chopped' (i.e. we don't get to the amount of minutes in time, not dry and millisecs). So, I was wondering if there is anyway to a

  (a) get the timestamp information full of a number of sgl (i.e. using the number of timestamp vi...)

  or

  (b) when you save a timestamp, is it possible to ignore the part date (would cause in my case)? I ask only assuming that I could skip the date part then sgl representation would be enough to give me up to milliseconds.

  Thanks for your time,

  Harry

  A timestamp uses 64 bits to contain the number of seconds since the 1,1,1904 and another 64-bit for the fraction of the second current. You can not far with 32 bits that SGL gives you and you cannot 'jump' the date, because it is an integral part of the number.

  One thing you can do is create a new era instead of 1904, but if you take 10 bits to get the resolution of ms, that leaves you with 22 bits for seconds, which isn't very long.

  What you can do is this:

  1. Take the timestamp and tick counter value at some point in time before you start (t0).
  
  
  2. Have a VI that will give you the run ms value by subtracting the number of cycles of t0 in the current number of cycles.
  
  
  3. Save the t0 timestamp in a header in your file.
  
  
  4. Save the real time as the time you get to step 2 (which is a 32-bit integer).
  
  
  5. When you want to calculate the current timestamp, just do t0 (from the header) + counter.

  This should be good for about 50 days of action, after which the number of cycles longer rolls.

  There are probably some existing formats where configure you this, but I have no experience with it.

• variable sharing, missing data, the timestamp even for two consecutively given

  Hello

  I have a problem with missing data when I read a published network shared variable.

  Host VI:

  In a host of VI on my laptop (HP with Windows XP Prof.) I write data to the shared Variable 'data '. Between two consecutively write operations is a minimum milliseconds of wait time. I use it because I want to make sure that the time stamp of each new value of data is different then a preview (variables shared the resolution is 1 ms)

  VI target:

  the VI target cRIO-9012 bed only of new data in the way that it compares the timestamp of a new value with the time stamp of the last value on a device in real time.

  Problem:

  rarely, I'm missing a data point (sometimes everything works fine for several hours, transfer thousands of data correctly above all of a sudden failure occurs). With a workaround, I'm able to catch the missing data. I discovered that the missing data have the timestamp exactly the same, then the last point of data read, is so ignored in my data 'legal '.

  To summarize, the missed value is written to the variable shared host, but ignores the target because its timestamp is wrong, respectively the same as the last value, despite the host waits for a minimum of 10 milliseconds each time before writing a new value.

  Note:

  The shared Variable is hosted on the laptop and configured using buffering.

  The example is simple only to display the function of principle, in real time, I also use a handshake and I guarantee that there is no sub - positive and negative.

  Simplified example:

  

  

  Question:

  Anyone has an idea why two consecutively data can have the same timestamp?

  Where timestamping (evil) Finally comes (System?)?

  What would be a possible solution (for the moment with shared Variables)?

  -> I tried to work around the problem with the clusters where each data gets a unique ID. It works but it is slower that comparing the timestamps and I could get performance problems.

  It would change anything when I animate the shared on the RT System Variable?

  Thanks for your help

• Timestamp of the external Signal triggered using the PCIe-6351

  Hello

  I use a PCIe-6351 to acquire externally triggered data.  My block diagram looks almost exactly at this link in the section A. Posttriggered Acquisition with a digital start triggering:

  http://www.NI.com/white-paper/4329/en

  As you can see he is a straightforward acquisition.  My trigger signal is on PFI0 and it is supposed to occur at regular intervals.  However, I started to suspect that it varies in time.  For example, if this is supposed to happen every 2 milliseconds it can range from 1.9 to 2.1 milliseconds.  Is it possible for DAQmx record the time at which each trigger occurs?  I realize that it will not be synchronized with the time on the PC, but as long as I can have a time stamp of each trigger I can subtract each time individual time of the first condition for the time between triggers.

  Thank you!

  Steve

  MR. O,.

  Thanks for the reply. My system is set up to acquire many points of data at a relatively fast pace, so I their stamp on the data acquisition card and only download on the PC once the acquisition is completed. My understanding is that writing to file measure vi set a timestamp whenever he writes to the file - not for each individual data point. Is this correct?

• Tektronix 3052 b timestamp question

  I think that this question will apply to many, if not all scopes for LabView interface, but it's the one that I tend to use.  I have managed to connect the field of LabView application over the network and can run the demo applications quite well.

  The particular test that I am running is that awaits a coming special trigger, after that is captures 10,000 samples of 1 microsecond increments each.

  If I don't have LabView and export the data file directly, it has a timestamp value that is right; check-in starts at-40 microseconds (that's the point that the scope begins to record the sample) and flows through ten following time milliseconds.

  The time stamp that is acquired by LabView, is however, formatted in this format:

  7:00:00.009 PM
  31/12/1903

  I was able noodles autour with parameters in time waveform diagram time string Date and get the display on the screen to display microseconds by entering a string "6u %" in the time format string string date/time format.  However, there are two outstanding issues:

  1. the string that is exported to Excel ends by displaying the calendar stuff.  No amount of playing with settings in Excel doesn't allow me to reduce the string to a single integer representing the number of microseconds past

  2. the point of departure - t0 - always by default is "0", which means that the data are not aligned to the correct microseconds in the graph of the wave.

  I've seen examples in the online support files, and that's how I got the point of being able to display microseconds.  No one seems to have attacked, however, the problem simply allow the exit number by the scope as "t0" to the passage in the spreadsheet file.  Anyone got any ideas?  There is little for me...

  Thank you

  Danielle

  Thought this might help; the graphic on the screen updates correctly, but the spreadsheet contains too much junk and not in the right format or starting point in time (see attachment)

  You can have any desired accuracy. Just change the format specifier.

  If you don't know what that means, put running context-sensitive help (which you should have any time, in any case), and move your mouse on the entry in the spreadsheet file.

• String to timestamp

  Hello

  I searched for a while now and still have no answer.

  I'm trying to convert a string to a timestamp.

  I can't find the correct expression to retrieve the seconds and milliseconds.

  I tried %S, %u or even % 3u. It still does not work.

  Any idea.

  

  Hello

  Try the format (without the quotation marks) string "% < %a-%m-%j="" %="" h.%m.%s.%3u=""> T.

  In your example, you had a '%' too behind the "M", also I replaced the comma with another period.

• Getting milliseconds of DATETIME SQL database Labview

  Hello

  I am trying to extract a timestamp of my MS SQL database and I don't get the milliseconds when I retrieve the data. Does anyone know how to program sql or labview, so I can get the timestamp set. In SQL, I set as datetime2. I'll appreciate any help. Thank you

  It seems that it is a TEEN driver problem, not specific to LabVIEW.  If you use the query

  SELECT Convert(varchar,Start_Test_Time,21) FROM Engine_Tests

  You can retrieve data in a string and convert it into a timestamp.

  You can also use

  SELECT DATEPART (msStart_Test_Time) FROM Engine_Tests

  to get just the part ms.  More information about DATEPART can be found here:
