Determines the offset to UTC in effect at the time and in the time
zone of @datetime.
The offset is the number of microseconds that you add to UTC time to
arrive at local time for the time zone (ie: negative numbers for time
zones west of GMT, positive numbers for east).
If @datetime represents UTC time, then the offset is always zero.
