TTimeZone (TeaVM Java class library 0.6.1 API)

java.lang.Object
- org.teavm.classlib.java.util.TTimeZone

All Implemented Interfaces:

Serializable, Cloneable
```
public abstract class TTimeZone
extends Object
implements Serializable, Cloneable
```
TimeZone represents a time zone offset, taking into account daylight savings.
Typically, you get a TimeZone using getDefault which creates a TimeZone based on the time zone where the program is running. For example, for a program running in Japan, getDefault creates a TimeZone object based on Japanese Standard Time.
You can also get a TimeZone using getTimeZone 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 TimeZone object with the following:
```
 TimeZone tz = TimeZone.getTimeZone("America/Los_Angeles");
 
```
You can use the getAvailableIDs method to iterate through all the supported time zone IDs. You can then choose a supported ID to get a TimeZone. 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:
```
 GMT[+|-]hh[[:]mm]
 
```
For example, you might specify GMT+14:00 as a custom time zone ID. The TimeZone that is returned when you specify a custom time zone ID does not include daylight savings time.
For compatibility with JDK 1.1.x, some other three-letter time zone IDs (such as "PST", "CTT", "AST") are also supported. However, their use is deprecated 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.
Please note the type returned by factory methods, i.e. getDefault() and getTimeZone(String), is implementation dependent, so it may introduce serialization incompatibility issues between different implementations.

    timezone - a TimeZone object.
  - setID
```
public void setID(String name)
```
    Sets the ID of this TimeZone.
    
    Parameters:
    
    name - a string which is the time zone ID.
  - setRawOffset
```
public abstract void setRawOffset(int offset)
```
    Sets the offset for standard time from GMT for this TimeZone.
    
    Parameters:
    
    offset - the offset from GMT in milliseconds.
  - useDaylightTime
```
public abstract boolean useDaylightTime()
```
    Returns whether this TimeZone has a daylight savings time period.
    
    Returns:
    
    true if this TimeZone has a daylight savings time period, false otherwise.
  - equals
```
public boolean equals(Object obj)
