AbsoluteTime

FilledSmallSquare AbsoluteTime[ ] gives the total number of seconds since the beginning of January 1, 1900, in your time zone.

FilledSmallSquare AbsoluteTime[ ] uses whatever date and time have been set on your computer system. It performs no corrections for time zones, daylight saving time, etc.

FilledSmallSquare AbsoluteTime[z] gives the result for time zone z. This is inferred by knowing your local date and time, and local time zone. The time zone is given as the number of hours to be added to Greenwich mean time to obtain local time.

FilledSmallSquare AbsoluteTime[ ] is always accurate down to a granularity of $TimeUnit seconds, but on many systems is much more accurate.

FilledSmallSquare There are 2208988800 seconds from the beginning of January 1, 1900 to the beginning of January 1, 1970 and 2840140800 seconds to the beginning of January 1, 1990.
