Accuracy of time stamp in file

[caunchman]

I'm rying to get the best way to display the system time at the start of my data collection.  Basically have the system time show up as the first sample +/- .010 seconds.  I am wondering if this VI will do it for me.  It is a basic stream to file VI with a "get cpu time" if the loop iteration is 0.  Let me know if you guys think this will do what I am trying to accomplish.

I'm having some trouble understanding why you are removing the start time information and then putting it back in. Your waveform data type has a t0. Have you looked at using the Export Waveforms to Spreadsheet File?

Also, the wiring of the iteration terminal to an indicator, then using a local variable, then doing a comparison is silly. If you want to do something only on the first iteration, wire the iteration terminal directly to the case statement selector.
