TimeZone

Synopsis

The TimeZone class represents a time zone; it is used with the Calendar and DateFormat classes. As an abstract class, TimeZone cannot be directly instantiated. Instead, you should call the static getDefault( ) method to obtain a TimeZone object that represents the time zone inherited from the host operating system. Or you can call the static getTimeZone( ) method with the name of the desired zone. You can obtain a list of the supported time-zone names by calling the static getAvailableIDs( ) method.

Once you have a TimeZone object, you can call inDaylightTime( ) to determine whether, for a given Date, daylight-savings time is in effect for that time zone. Call getID( ) to obtain the name of the time zone. Call getOffset( ) for a given date to determine the number of milliseconds to add to GMT to convert to the time zone.
