Sorry, not sure what you're getting at here. The UTC_Time_Offset will change
due to daylight saving, so it can never be a constant.
For Windows, I can't find anything that states if "GetTimeZoneInformation"
is atomic or not and this is the routine that returns the time structure.
But even if it isn't atomic it's only going to be 'wrong' at most twice a
year and only for a second or so each time.
