• Measure the time in seconds each time run you a VI

  Dear people,

  I'm trying to measure the speed of a wheel using a magnetic sensor and other settings in the vehicle. What I also need to document in my project is the time elapsed (in seconds) each time that you run the program. Is there a way where you can measure the elapsed time in seconds in labview?

  Any sort of suggestions or examples would be useful.

  Below is an example of how I wanted my final to watch output file.

  Time (sec) | Speed (mph). Acceleration |

  0                    23                 5

  1                    24                 6

  2                    25                 7

  Thank you in advance!

  Rahul-

  Hi iZACHdx,

  That's what I was looking for exactly! Thanks for the simple example.

• Daylight Saving Format Date/Time String vs get time in seconds

  Hi all

  I have developed a real-time application using a cRIO 9074 which has two loops. The first gathers data and records the time using the module of ' string of Format Date/time ' with the following time sting: '%d/%m/%Y % H: %m ". The output is a sting with mouth/day/year hour: minute.

  The second loop Gets the cRIO time using the module "get Date/Time in Seconds ' and the output of timestamp is sent by a shared variable for an application that is running on a local computer.

  The problem started Sunday last with DST. With the help of MAX I am able to see that the time of cRIO is bad (1 hour less) and that him "automatically adjust clock for daylight saving time" is not checked and gray, so I am not able to change it.

  The time of the first loop by using the "Date and time Format string' returns the time elapsed between the cRIO (1 hour late), however the time of the second loop is OK. I have manually corrected time using MAX, so now the first loop is correct, and the second is now over an hour.

  Any ideas?

  Dear RavensFan, thank you very much for your answer.

  However, this was not the problem. Apparently the result with or without the element of DST is the same. I solved the problem, for now, by changing a parameter not on the function "get Date/Time in Seconds" but on the time stamp indicator.

  By right clicing the indicator and go to the display Format and the advanced editing mode, I have changed the Format string to a universal time container of this: %< %="" h:="" %m="">< t="" %="" ^="">< %="" h:="" %m=""><>

  Apparently the time from the 'get time in seconds' is still an hour longer, but now it is correctly displayed.

• calculate the time in seconds, the day of the year and year

  I have a data file where they record three columns, the seconds elapsed since midnight, day of the year and the year.  I am creating a timestamp of LabVIEW from these three numbers.  Of seconds elapsed since midnight, I can create seconds, minutes and hours.  If I feed in a cluster of time with the day of the year and the year, the timestamp of output is 0.  Does not work.  Although an input of the day of the year element, the Date and time with seconds function apparently requires day for months and months to work.

  The only solution I can imagine at this stage is to calculate the month and the day of the day of the year, which would imply a choice of the month table and a check of the leap year.

  Smart solutions, I'm missing?

• tick count vs get time in seconds

  Hello

  I have a question about dt different then as 'number of cycles' and "get time in seconds" on a loop.

  I am attaching the picture which should describe the problem.

  Why is there a difference and what would be the best to do?

  Number of cycles vs. get date/time in second do roughly the same thing, but if you use functions to calculate the time difference, you should be aware that tick count will finally make a loop around.

  Regarding your block digram, you have a table that are used to calculate the elapsed time for each iteration of the loop, and it will always be 150ms, because that is the job of the time – the loop to ensure that it completestobegin each loop to the exact amount of time specified, which is 150ms in your case.  However, regardless of the inside, the loop can be executed at any time during the 150ms you have allocated to the loop, i.e., you 150ms to run everything that's in the loop, but when run the code in the loop exactly is indeterminate.

  However, it seems that clock Tick would give you a pretty consistent result, 150ms.  It is possible that the execution time for the clock to tick is more consistent than the other function.

  Anecdote:

  Differnce between the counties of the tick will always be correct even when it rolls.

  Time loop determines when it starts, the code that runs in it determines when it ends.  If it was the other way around I would be snapping this code that takes 5 minutes to run in a defined time loop to traverse once per second.

  I agree with Yair you see the resolution in the timestamps of OS.

• Digital time with seconds!

  Does anyone know if I can get a face somewhere for my Apple Watch who has time Digial seconds? I work in health care and it would be so much easier if I can use a digital face.

  Hello

  This feature is not currently available as part of watchOS - and it is not currently possible to install third-party Apple Watch dials.

  If you do that Apple considers adding a dial with digital display of the time including seconds, you can do so here:

• Get the time in seconds

  How can I get block 'get the date and time' a few seconds (all time in seconds)? I try the conversation, display format; but can not get all the time in seconds!

  Hi hlod,.

  Here are two versions for the second of the current timestamp:

  

  One of the top just converts timestamp seconds (since then), while the lower part, you get the current "seconds" value of the timestamp. The next time you better explain what you want...

  P.S.:

  Who did you 'conversation' with?

• The function "Time in seconds" does not work as I expect. Can someone tell me why?

  In the attached VI my hour entry to the function "Time in seconds" is 11, but the output is 12:09. Why is he 12:09 and not 11:09?

  Thank you.

  I tried and it works, but I don't know why or how it works.

  Tried what idea? If you talk about my idea above, position 10 of the cluster is "is DST', look at the help. The only way to make sense would be to identify the components of the cluster correctly, as NEITHER should have done, so the names will get to the Unbundle propigated.

• time and Date/time in seconds

  Judging by some than others, it is a long-term problem.

  With the help of LV 8.6 incidentally.

  I'm trying to convert a date/time for LV timestamp format using the vi Date/time of seconds"." Recently converted time has been displayed as an hour before (I am in UK & DST is now in effect)-a problem I thought that I had healed.

  I wrote a simple test for the VI program (create a constant of the entry and use it to drive a bundle of cluster name to set s/hour/day/month/year etc.) With the function in a loop (0.5s) I have controls to change the month and isDST in the folder & isUTC in the function call - and displays the output in the form of stamp and as EXT. If the month is Pre-dst, everything is ok (for example, an hour of 10 stays at 10), if the month is 5 (DST) then the hour at 11 awards - unless isDST is set to 1 and isUTC set to false. but when this combination of controls is used with the months, a value of 2 - time becomes 9.

  As I say, I thought I had it healed and remember something on the Windows DST flag - and I had recently exchanged PCs - so I turned off the Windows DST (wDST) - no effect. This morning, I rebooted the PC to watch once again this program - to my astonishment, that the 'problem' had gone. I then checked the wDST it was always off. I stopped the criterion VI and closed and on wDST when you attempt to reload the VI of test I had a very weird error message telling me that my VI disk did not 'part of LV in memory' and inviting me to "come back". I stop LV completely rebooted and got the same effect. I restarted the PC and 'come back' was gone and the problem returns (wDST checked).

  So my initial dose had been disable wDST on my m/c origin.

  However, my query is what is the point of setting Date/time to seconds isUTC - it seems doing nothing like what he promises. What little LV blocks also on after I closed the program remember probably the DST Windows defining - maybe wrongly?

  
  

• Is there an easy way to get a Date/time string seconds?

  I have 2 strings of the format depending on whether I would like to convert in seconds (since 1900). I need this value to set the t0 in a field.

  Date: ' 30/06/2014 '.

  "Time: '16:06 ' 08."

  Is there a CVI function that will do this conversion for me? If not, is there an easy way to do it?

  Thank you!

  This code should do what you want:

  
  
  
  static time_t  calt;
  
  struct Shared  tm tm;
  
  public static char    msg [64];
  
  public static int     AA, mm, DD, hh, mn ss;
  
  strcpy (msg, ' 2014/06/30 16:06:08 ');
  Extract the date/time string component
  
  Scan (msg, "%d [x] %d [x] %d [x] %d [x] [x] %d %d", & mm, dd, and yy, & hh, & mn, &ss);)
  Transfer to a struct tm components
  
  TM.tm_hour = hh;
  
  TM.tm_min  = mn;
  
  TM.tm_sec  = ss;
  
  TM.tm_year = yy - 1900;
  
  TM.tm_mon  = mm - 1;

• setting the time adding seconds

  Hi guys, I'm stuck and I need help with this one and its emergency situation. I don't have 1 more week to test because I needed to get the data as soon as POSSIBLE. I have this test I've done 1 week, but I messed up on something. I didn't have seconds on my get date/time.  My colleague needs the second in my test in order to get his test results.

  can anyone help me please with this.

  

  on column B, this here a way to generate seconds with labview or excel so that he would not lose the HR/min or its order.

  Please someone help me.

  Hi krispiekream,

  I hate to be the bearer of bad news, but it seems that the worksheet was written as csv - and column B was written exactly as it appears in your message.  In other words, there is no detail "seconds" to display. If a LabVIEW program creates the csv data, this program can be (should be) modified to include the details in seconds!

  Chance/Cheers.

• Problem of time in seconds

  OK, here's the thing: I use get current date/time, I convert it to a string and the string is saved in a CSV - text -.

  Then, I built in a feature to plot the data previously saved on a XY Chart. I use the search string to find the values of time and convert to a timestamp.

  Works like a charm... BUT I noticed when I moved with my VI to another platform for some reason, it has a different formatting of the time system, this is the case:

  My 64 bit:
  08:16:48.978 PM 02/08/2010

  Any other 32-bit windows:
  08:25:02, 055 02/08/2010

  Another problem is that it uses a comma instead of a period for fractions of a second.

  So now, here is the million dollar question: where can I change this, preferably in labview? I want to get the time in AM PM regardless of the platform and use the point for fractions of a second.

  Thank you!

  '

  This is a possibility, as you use the ' Date/Time Format string"you can use the same format string to parse the timestamp:

  

  The fact that a "," is used is a bug in LabVIEW and still not fixed. Where should you get fractions of a second? The timestamp data itself always have lots of information about the timestamp. Representation (whether as indicator of string or timestamp) can be made in any way (same time zone independent).

• OS5 stops Javascript when the backlight is off or time &gt; 10 seconds - is this a problem for the WebWorks applications?

  I read that the OS5 browser stops all scripts once the backlight turns off, or if the script takes longer than 10 seconds to run. The problem is that the scripts will automatically restart (!). I really hope this isn't the case for the WebWorks applications, I can't have the app stop working if the backlight turns off. If the general development of BB moves towards HTML5 and JS and expects to have success, this kind of problem cannot exist.

  WebWorks for OS5 doing?

  No, this time-out does not occur for applications WebWorks... only for pages running in the browser.
