Overview
The example shows a way to write/read a time stamp to a text file.

 


Description
The following example is a good way to write/read a time stamp to a text file. Please note that the milliseconds component of the timestamp is lost in this process. Most DAQ File I/O operations will have this functionality built in but if a program developer wanted to integrate it on a lower level, this would be one way to do it.

 


Requirements

  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  1. Download the attached folder to your computer
  2. Open the VI "Proper Time Stamp File IO 2012 NIVerified.vi"
  3. Run the VI

Bug:

Times of 12:xx PM or 12:xx AM give wrong output

Examples:

Input:

12:20:09.848 PM

8/21/2014

Output:

12:20:09.000 AM

8/22/2014

note that PM became AM and we're now in the next day.

OR

Input:

12:20:09.848 AM

8/21/2014

Output:

12:20:09.000 PM

8/21/2014

note that AM became PM
