# AbsoluteTime

 gives the total number of seconds since the beginning of January 1, 1900, in your time zone. AbsoluteTime[{y, m, d, h, m, s}] gives the absolute time specification corresponding to a date list. AbsoluteTime["string"] gives the absolute time specification corresponding to a date string. AbsoluteTime[{"string", {"e1", "e2", ...}}] takes the date string to contain the elements "ei".
• uses whatever date and time have been set on your computer system. It performs no corrections for time zones, daylight saving time, etc.
• is always accurate down to a granularity of \$TimeUnit seconds, but on many systems is much more accurate.
• Shorter lists can be used in AbsoluteTime[{y, m, ...}]: {y} is equivalent to {y, 1, 1, 0, 0, 0}, {y, m} to {y, m, 1, 0, 0, 0}, etc.
• Values of m, d, h, m, s outside their normal ranges are appropriately reduced. Non-integer values of d, h, m, s can also be used.  »
