<hr><a name="_details"></a><h2>Detailed Description</h2>
<code><a class="el" href="classTimeZone.html">TimeZone</a></code> represents a time zone offset, and also figures out daylight savings.
<p>
Typically, you get a <code><a class="el" href="classTimeZone.html">TimeZone</a></code> using <code>createDefault</code> which creates a <code><a class="el" href="classTimeZone.html">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">TimeZone</a></code> object based on Japanese Standard Time.<p>
You can also get a <code><a class="el" href="classTimeZone.html">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">TimeZone</a></code> object with: <blockquote> <pre>
<a class="el" href="classTimeZone.html">TimeZone</a> *tz = <a class="el" href="classTimeZone.html#f938674c0b8db09936af7d6843bc37b1">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">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">TimeZone</a></code> that is returned when you specify a custom time zone ID does not include daylight savings time.<p>
<a class="el" href="classTimeZone.html">TimeZone</a> is an abstract class representing a time zone. A <a class="el" href="classTimeZone.html">TimeZone</a> is needed for <a class="el" href="classCalendar.html">Calendar</a> to produce local time for a particular time zone. A <a class="el" href="classTimeZone.html">TimeZone</a> comprises three basic pieces of information: <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">TimeZone</a>; subclasses of <a class="el" href="classTimeZone.html">TimeZone</a> may handle daylight savings time and GMT offset in different ways. Currently we only have one <a class="el" href="classTimeZone.html">TimeZone</a> subclass: <a class="el" href="classSimpleTimeZone.html">SimpleTimeZone</a>.) <p>
The <a class="el" href="classTimeZone.html">TimeZone</a> class contains a static list containing a <a class="el" href="classTimeZone.html">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>
To create a new <a class="el" href="classTimeZone.html">TimeZone</a>, you call the factory function <a class="el" href="classTimeZone.html#f938674c0b8db09936af7d6843bc37b1">TimeZone::createTimeZone()</a> and pass it a time zone ID. You can use the <a class="el" href="classTimeZone.html#c0cd984db0f0fa9f2b06e0edce159db5">createEnumeration()</a> function to obtain a list of all the time zone IDs recognized by <a class="el" href="classTimeZone.html#f938674c0b8db09936af7d6843bc37b1">createTimeZone()</a>. <p>
You can also use <a class="el" href="classTimeZone.html#f4f013eb9ebab83042cfbc719c625e66">TimeZone::createDefault()</a> to create a <a class="el" href="classTimeZone.html">TimeZone</a>. This function uses platform-specific APIs to produce a <a class="el" href="classTimeZone.html">TimeZone</a> 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), <a class="el" href="classTimeZone.html#f4f013eb9ebab83042cfbc719c625e66">TimeZone::createDefault()</a> will return a <a class="el" href="classTimeZone.html">TimeZone</a> for Japanese Standard Time ("Asia/Tokyo").

There may be several times zones with the same GMT offset that differ in the way they handle daylight savings time. For example, the state of Arizona doesn't observe daylight savings time.
