/**
|
|
* This class represents a time zone offset and handles daylight savings.
|
|
*
|
|
* You can get the default time zone with <code>getDefault</code>.
|
|
* This represents the time zone where program is running.
|
|
*
|
|
* Another way to create a time zone is <code>getTimeZone</code>, where
|
|
* you can give an identifier as parameter. For instance, the identifier
|
|
* of the Central European Time zone is "CET".
|
|
*
|
|
* With the <code>getAvailableIDs</code> method, you can get all the
|
|
* supported time zone identifiers.
