$SystemTimeZone
gives the current time zone for the computer system on which the Wolfram System is being run.
Details

- The time zone gives the number of hours that must be added to Greenwich Mean Time (GMT) to obtain local time.
- $SystemTimeZone is set at the beginning of your Wolfram System session to the time zone specified by the computer system on which it is running.
- The Wolfram System assumes that the time returned by the system clock on your computer system is for the time zone corresponding to $SystemTimeZone.
