Data Type: Time

The time and date on which the current object last changed.

Example: 23 Sep 1998 09:54:51 -0700.

The number at the end of the value for time and date is the number of hours behind (to the west) or ahead (to the east) of Coordinated Universal Time (UTC). If the value is positive, it is the number of hours the local time is ahead of UTC. If the value is negative, it is the number of hours the local time is behind UTC. In the example, the number -0700 tells you the local time is 7 hours behind (or to the west) of UTC.

Note that Greenwich Mean Time (GMT) is equivalent to UTC when fractions of a second are not considered important.

For more information about UTC, see the National Institute of Standards and Technology Web site at http://www.nist.gov/.
