Recording data in System Time

I'm writing a program to record lab data, and instead of time in seconds starting from 0, I want to have data points recorded by system or computer time so I can compare the data from two or more computers once it's all been recorded in excel. 

Any ideas?

Have you looked at the Timing functions?  The ones called Get Date/Time do (here's the Big Surprise ...) Get Date/Time.  If you look at the Help, you will see their default behavior is to return the current Date and Time.

I am using the write to measurement file express vi, and those do not provide the date in the proper data type to put into the signal input. 

Is there a way to convert the time data to the proper data type?

Did you notice that Write to Measurement File has a setting to have Time saved as Absolute (rather than Relative) Time?

P.S. -- you will get help much quicker by posting code and being clear as to the real problem.

The express VI saves data in a very specific format and is difficult to change The t0 should be the actual start time. Try Export Waveforms to File or create your own format with Write to Spreadsheet or the lower level Write to Text File.
