    {
        /*
         * Returns:an array of IDs.
         */
        String[] idArray = TimeZone.getAvailableIDs();
        for (String id : idArray)

TimeZoneDemo2.java

import java.util.TimeZone;

public class TimeZoneDemo2
{
    public static void main(String[] args)
    {
        /*
         * Parameters:
         *
         * rawOffset - the given time zone GMT offset in milliseconds.
         *
         * Returns:an array of IDs, where the time zone for that ID
         * has the specified GMT offset. For example,
         * "America/Phoenix" and "America/Denver" both have GMT-07:00,
         * but differ in daylight saving behavior.
         */
        String[] availableIDArray = TimeZone.getAvailableIDs(3600000);

        System.out.println("Available Ids for offset are: ");
        for (String availableID : availableIDArray)
        {
            System.out.println(availableID);
        }
    }
}
