Understanding Timestamp

[Lynniz]

Hi All,

I would like to get some clarifications on timestamp.  My program is displaying data collected with timestamps in a waveform chart.  I would like to have the timestamps to be either in UTC or the time in my timezone.  First I thought the LabView timestamp is in sync with Window's computer time, but when I changed the computer time to UTC and at 1:33 PM, the timestamp in LabView displayed as 6:33 AM.  I am really confused.  Could anyone explain to me how the Labview timestamp is generated?  Is there a setting that I can changed in LabView to sync up with computer time? 

Another problem that I have encountered is when I read the data file in excel (timestamp and raw data in tdms format) on a different computer with different time zone, the original timestamps were off by couple hours.  How do I correct for that? 

Sorry for the long explanation and questions.

Thank you,

Lynniz

This one is a little tricky. What you need to do is to format the X-Axis. You can find a picture of what you need to do in this message: http://forums.ni.com/t5/LabVIEW/How-can-I-get-LabVIEW-7-1-to-display-the-UTC-time-03-11-2007/m-p/499....

As for your other question, this is a frequently asked question, so searching the forum will yield this as a common problem. Excel uses a different zero time than LabVIEW. The most common solution is to add an offset.
