CentOS timezone config

CentOS timezone config files and directories

  • /usr/share/zoneinfo/ – The system timezone directory contains the files as per timezone name. For example, the file /usr/share/zoneinfo/America/New_York represents time zone for New York.
  • /etc/localtime – It is a symlink to the file localtime or to the correct timezone file in the system located in /usr/share/zoneinfo/ directory.

How do I see the current time zone?
Type the date command or the ls command:

$ date
$ ls -l /etc/localtime

Change the current timezone:
mv /etc/localtime /root/localtime.old
ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime
Change the current timezone in CentOS 7
To find list of all available time zones, run:
# timedatectl list-timezones
##*** Grep possible Asian timezones ***##
# timedatectl list-timezones | grep Asia
timedatectl set-timezone time_zone
In this example, set timezone to America/Chicago
# timedatectl set-timezone America/Chicago
