TimeZone represents a time zone offset, and also figures out daylight
* savings.
*
*
* Typically, you get a TimeZone using createDefault
* which creates a TimeZone based on the time zone where the program
* is running. For example, for a program running in Japan, createDefault
* creates a TimeZone object based on Japanese Standard Time.
*
*
* You can also get a TimeZone using createTimeZone along
* with a time zone ID. For instance, the time zone ID for the US Pacific
* Time zone is "America/Los_Angeles". So, you can get a Pacific Time TimeZone object
* with:
* \htmlonly
\endhtmlonly
*
* TimeZone *tz = TimeZone::createTimeZone("America/Los_Angeles");
*
* \htmlonly\endhtmlonly
* You can use getAvailableIDs method to iterate through
* all the supported time zone IDs. You can then choose a
* supported ID to get a TimeZone.
* If the time zone you want is not represented by one of the
* supported IDs, then you can create a custom time zone ID with
* the following syntax:
*
* \htmlonly\endhtmlonly *\endhtmlonly * * For example, you might specify GMT+14:00 as a custom * time zone ID. The* GMT[+|-]hh[[:]mm] ** \htmlonly
TimeZone that is returned
* when you specify a custom time zone ID does not include
* daylight savings time.
*
* TimeZone is an abstract class representing a time zone. A TimeZone is needed for
* Calendar to produce local time for a particular time zone. A TimeZone comprises
* three basic pieces of information:
* * The TimeZone class contains a static list containing a TimeZone object for every * combination of GMT offset and daylight-savings time rules currently in use in the * world, each with a unique ID. Each ID consists of a region (usually a continent or * ocean) and a city in that region, separated by a slash, (for example, US Pacific * Time is "America/Los_Angeles.") Because older versions of this class used * three- or four-letter abbreviations instead, there is also a table that maps the older * abbreviations to the newer ones (for example, "PST" maps to "America/Los_Angeles"). * Anywhere the API requires an ID, you can use either form. *
* To create a new TimeZone, you call the factory function TimeZone::createTimeZone() * and pass it a time zone ID. You can use the createEnumeration() function to * obtain a list of all the time zone IDs recognized by createTimeZone(). *
* You can also use TimeZone::createDefault() to create a TimeZone. This function uses
* platform-specific APIs to produce a TimeZone for the time zone corresponding to
* the client's computer's physical location. For example, if you're in Japan (assuming
* your machine is set up correctly), TimeZone::createDefault() will return a TimeZone
* for Japanese Standard Time ("Asia/Tokyo").
