<div class="textblock"><p><code><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></code> represents a time zone offset, and also figures out daylight savings. </p>
<p>Typically, you get a <code><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></code> using <code>createDefault</code> which creates a <code><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></code> based on the time zone where the program is running. For example, for a program running in Japan, <code>createDefault</code> creates a <code><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></code> object based on Japanese Standard Time.</p>
<p>You can also get a <code><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></code> using <code>createTimeZone</code> along with a time zone ID. For instance, the time zone ID for the Pacific Standard Time zone is "PST". So, you can get a PST <code><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></code> object with: <blockquote> <pre>
<a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> *tz = <a class="el" href="classTimeZone.html#a11ffc5d14d3956478110909e6dca01b6" title="Creates a TimeZone for the given ID. ">TimeZone::createTimeZone</a>("PST");
</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><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></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:</p>
<blockquote> <pre>
GMT[+|-]hh[[:]mm]
</pre> </blockquote><p>For example, you might specify GMT+14:00 as a custom time zone ID. The <code><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a></code> that is returned when you specify a custom time zone ID does not include daylight savings time.</p>
<p><a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> is an abstract class representing a time zone. A <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> is needed for <a class="el" href="classCalendar.html" title="Calendar is an abstract base class for converting between a UDate object and a set of integer fields ...">Calendar</a> to produce local time for a particular time zone. A <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> comprises three basic pieces of information: </p>
<ul>
<li>
A time zone offset; that, is the number of milliseconds to add or subtract from a time expressed in terms of GMT to convert it to the same time in that time zone (without taking daylight savings time into account). </li>
<li>
Logic necessary to take daylight savings time into account if daylight savings time is observed in that time zone (e.g., the days and hours on which daylight savings time begins and ends). </li>
<li>
An ID. This is a text string that uniquely identifies the time zone. </li>
</ul>
<p>(Only the ID is actually implemented in <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a>; subclasses of <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> may handle daylight savings time and GMT offset in different ways. Currently we only have one <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> subclass: <a class="el" href="classSimpleTimeZone.html" title="SimpleTimeZone is a concrete subclass of TimeZone that represents a time zone for use with a Gregoria...">SimpleTimeZone</a>.) </p>
<p>The <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> class contains a static list containing a <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a> 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, Pacific Standard 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/LosAngeles"). Anywhere the API requires an ID, you can use either form. </p>
<p>To create a new <a class="el" href="classTimeZone.html" title="TimeZone represents a time zone offset, and also figures out daylight savings. ">TimeZone</a>, you call the factory function <a class="el" href="classTimeZone.html#a11ffc5d14d3956478110909e6dca01b6" title="Creates a TimeZone for the given ID. ">TimeZone::createTimeZone()</a> and pass it a time zone ID.
