Daylight Saving Time off by one hour

[Cyrille_D.]

Take a close look at the attached screenshots. Both cRIO and PC are synchronized to the same time server. Yet, there is 1 hour & 1 minute difference on PST8PDT, or "only" 1 minute difference on PST8.

Is it a bug???

I notice the same thing in LabVIEW when converting the current time in secondes with the DBL converter.

Good Afternoon,

What time server are you synchronizing the computer and cRIO to?  Here is a useful KnowledgeBase article to follow to make sure you have it setup correctly.  I hope you have a great rest of the day!

I was using a Canadian time server (time.nrc.ca).

However, when I switched to a NIST server on the cRIO, the time is no longer offset.

A bit strange: I would expect every time server to give the same time in the same format.

Anyway, using NIST server works!

I think those Canadian servers run on metric time.
