NSTimeZone
| NSTimeZone | Mac OS X 10.0 |
This class represents a time zoneobjects that store information about a geographic time zone, such as the name, abbreviation, time from GMT, whether or not daylight savings is in effect, and so on.
NSTimeZone is toll-free bridged with the Core Foundation type CFTimeZone. As such, NSTimeZone objects can be used interchangeably with the CFTimeZone pointer type, CFTimeZoneRef.
