Updating Time Zone Information

The information contained in the list of available time zones/locations is obtained from the Java time zone implementation. This includes both the appropriate time zone offset and locale-specific daylight saving time information. While the time zone offset is of constant value determined by a geographical location, daylight saving time rules may change over time. These changes should be reflected in the latest version of Java time zone implementation.

Should the need to update your locale-specific time zone/saving time information arise, update to the latest version of Java.
