For example, for a program running in Japan, <code>getDefault</code> creates a <code>TimeZone</code> object based on Japanese Standard Time. <p> You can also get a <code>TimeZone</code> using <code>getTimeZone</code> along with a time zone ID. For instance, the time zone ID for the U.S. Pacific Time zone is "America/Los_Angeles". So, you can get a U.S. Pacific Time <code>TimeZone</code> object with: <blockquote> <pre> TimeZone tz = TimeZone.getTimeZone("America/Los_Angeles"); </pre> </blockquote> You can use <code>getAvailableIDs</code> method to iterate through all the supported time zone IDs. You can then choose a supported ID to get a <code>TimeZone</code>. 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: <blockquote> <pre> GMT[+|-]hh[[:]mm] </pre> </blockquote> For example, you might specify GMT+14:00 as a custom time zone ID. The <code>TimeZone</code> that is returned when you specify a custom time zone ID does not include daylight savings time. <p> For compatibility with JDK 1.1.x, some other three-letter time zone IDs (such as "PST", "CTT", "AST") are also supported. However, <strong>their use is deprecated</strong> because the same abbreviation is often used for multiple time zones (for example, "CST" could be U.S. "Central Standard Time" and "China Standard Time"), and the Java platform can then only recognize one of them.<P><DL><DT><B>Since: </B><DD>JDK1.1</DD><DT><B>See Also: </B><DD><A HREF="../../java/util/Calendar.html"><CODE>Calendar</CODE></A>, <A
