Time Zone change is required Some times when we move our Machines(VMs) from one location to another location.
You can easily change timezone in RHEL/CentOS using the
following methods.
Check which time zone you are in by using date command.
Example:
[root@bsrtech ~]# date
Fri Jun 1 12:26:53
IST 2018
Actually My Machine(VM) is moved from India to US(Eastern
Time) Data Centre. Here i am showing
change time zone from IST to EDT.
In Linux timezone data is taken from /etc/localtime which is
linked to one of the file located in /usr/share/zoneinfo/*
Delete the current localtime file under /etc/ directory,
before deleting backup the localtime file
[root@bsrtech ~]# cd /etc
[root@bsrtech ~]# cp /etc/localtime
/etc/localtime_bkp_8MAR2018
[root@bsrtech ~]# rm localtime
All US timezones are located under the
/usr/share/zoneinfo/US directory as shown below.
[root@bsrtech US]# ls
Alaska Arizona
Eastern Hawaii Michigan Pacific
Samoa
Aleutian Central
East-Indiana Indiana-Starke Mountain
Pacific-New
Note: For other
country timezones, browse the /usr/share/zoneinfo directory.
Link the Eastern file from the above US directory to the
/etc/localtime directory as shown below.
[root@bsrtech US]# # ln -s
/usr/share/zoneinfo/US/Eastern
/etc/localtime
Now the timezone on your Linux system is changed to US
Eastern time as shown below.
[root@bsrtech ~]# date
Fri Jun 1 03:19:21
EDT 2018
Note: The date
command can be used for both viewing and changing the date and time. Change the
Time using date Command
Set Manual Time
[root@bsrtech ~]# date -s "01 JUNE 2018 02:34:00"
FRI June 1 02:34:00
EDT 2018
