[foxboro] DST on our New P91

On our old 51B system our last Process Dude set up a time sync to our PI sever 
(Windows). It checked the PI server time and verify that they synced, if not 
reset the Foxboro box to match. This handle the Daylight Savings time change 
fine. 
 
I was told that this would not work on the new machine. As in we would lose 
data in our AIM* historian (overwrite or leave a one hour gap depending on 
spring or fall). We only use the AIM * for an operator visual info at their 
control console trending and such. We use PI as our data collection and report 
historian, (one reason because it can handle DST with out overwriting data.
 
Anyway, our current plan is to just have the operator reset system time @ 
2:00AM on 11/10. Any ideas on how to do this better or automate it as we had in 
the past. Since these are both are windows machines I figure it should be 
pretty easy.
 
Our current settings on our machines are P91 GMT with the time set to local.  
PI Server  GMT - 9:00 (Alaska) and set to auto adjust DST.
 
 
Thank you for your support.
