Time Zone information in Java

Concept :

A time zone is a region where the same standard time is used. In java for getting time zone we have following 2 methods in TimeZone class that is present in java.util.* package.

1. static TimeZone getDefault() - Provides default time zone. It gets the time zone by System date. 
2. static TimeZone getTimeZone(String id) - Provides time zone based on ID. For example - if ID is "Europe/London" then it returns time zone in GMT.
