That works fine.  Time sync protocols use an absolute time (i.e., UTC, although any number that 
includes a time zone would do).

Later you say the data must be logged using local time.  So EPA regulations require all your 
customers to be located where DST is not observed (no wonder there are so many jobs in Phoenix ;-).

The time server (NTP or SNTP) doesn't do DST, Windows system time does.  You can tell it not to and 
then it won't be using local time.

It sounds like your logging is a bit deficient if you don't log the time zone and you allow data 
from different time zones to overwrite each other.

But I think that if you set up a time server and sync from it any problems you have will be Windows 
problems and not time server problems.
