I need to convert different timezone to my local time and date?
Using date command you can convert to different date and time zones to your local time zone defined by:
$ ls -l /etc/localtime
lrwxrwxrwx. 1 root root 38 Jun 11 13:08 /etc/localtime -> ../usr/share/zoneinfo/Australia/Sydney
In the below example we will convert UTC time to EST:
$ date -d '2014-06-26 23:00 UTC'
Fri Jun 27 09:00:00 EST 2014

Following the above timezone conversion example to convert from CEST (Central European Summer Time ) we do:
$ date -d '2014-06-26 23:00 CEST'
Fri Jun 27 07:00:00 EST 2014
