| /** |
| * {@icuenhanced java.util.TimeZone}.{@icu _usage_} |
| * |
| * <p><code>TimeZone</code> represents a time zone offset, and also computes daylight |
| * savings. |
| * |
| * <p>Typically, you get a <code>TimeZone</code> using {@link #getDefault()} |
| * which creates a <code>TimeZone</code> based on the time zone where the program |
| * is running. 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 {@link #getTimeZone(String)} |
| * 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 the {@link #getAvailableIDs()} 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><strong>Note:</strong> Starting from ICU4J 4.0, you can optionally choose |
| * JDK <code>TimeZone</code> as the time zone implementation. The TimeZone factory |
| * method <code>getTimeZone</code> creates an instance of ICU's own <code>TimeZone</code> |
| * subclass by default. If you want to use the JDK implementation always, you can |
| * set the default time zone implementation type by the new method |
| * <code>setDefaultTimeZoneType</code>. Alternatively, you can change the initial |
| * default implementation type by setting a property below. |
| * |
| * <blockquote> |
| * <pre> |
| * # |
| * # The default TimeZone implementation type used by the ICU TimeZone |
| * # factory method. [ ICU | JDK ] |
| * # |
| * com.ibm.icu.util.TimeZone.DefaultTimeZoneType = ICU |
| * </pre> |
| * </blockquote> |
| * |
| * <p>This property is included in ICUConfig.properties in com.ibm.icu package. When the |
| * <code>TimeZone</code> class is loaded, the initialization code checks if the property |
| * <code>com.ibm.icu.util.TimeZone.DefaultTimeZoneType=xxx</code> is defined by the system |
| * properties. If not available, then it loads ICUConfig.properties to get the default |
| * time zone implementation type. The property setting is only used for the initial |
| * default value and you can change the default type by calling |
| * <code>setDefaultTimeZoneType</code> at runtime. |
