The TimeZone class implements a time zone information source for client
applications. The time zone object is instantiated from a TimeZoneData object,
which is made from a JSON string that contains all the data needed for
the specified time zone. Applications can instantiate a time zone statically,
in which case the data could be retrieved from
the TimeZoneConstants
class. Applications can also choose to instantiate from a string obtained
from a server. The time zone string contains locale specific data. If the
application only uses a short representation, the English data will usually
satisfy the user's need. In the case that only the time zone offset is known,
there is a decent fallback that only uses the time zone offset to create a
TimeZone object.

From class
java.lang.Object
|
This factory method creates a time zone instance from a JSON string that contains the time zone information for desired time zone. Applications can get such a string from the TimeZoneConstants class, or it can request the string from the server. Either way, the application obtains the original string from the data provided in the TimeZoneConstant.properties file, which was carefully prepared from CLDR and Olson time zone database.

Returns the daylight savings time adjustment, in minutes, for the given date. If daylight savings time is in effect on the given date, the number will be positive, otherwise 0.

Returns time zone id for this time zone. For time zone objects that have been instantiated from a time zone offset, the POSIX time zone id will be returned.
