How to Covert the Time Zone in Linux Server?

Below steps are used to Covert the GMT time zone UTC time zone.

1. Check the current Time zone.

[root@testserver ~]# date
Tue Feb  7 07:51:59 GMT+6 2017

2. List the available Time zone (Check the UTC is abavilable or not)

3. Copy the UTC Time Zone file to /etc/localtime & run the date command to verify.

[root@testserver ~]# cp /usr/share/zoneinfo/Etc/UTC /etc/localtime
cp: overwrite `/etc/localtime'? y
[root@testserver ~]#
[root@testserver ~]# date -u
Tue Feb  7 13:52:32 UTC 2017
[root@testserver ~]# date
Tue Feb  7 13:52:33 UTC 2017

Some special case (RHEL 6.9), need to update the /etc/sysconfig/clock file as well.

[root@testserver ~]#cat  /etc/sysconfig/clock
ZONE="Asia/Kuala_Lumpur"
