Changing Timezone and Updating the Time


  1. Log in as root
  2. To check the current time use the ‘date’ command.
  3. Go to the directory /usr/share/zoneinfo. It will give you a list of all available time zones. Choose the most appropriate for your area.
  4. I usually like backups, so backup the previous timezone configuration by copying it to a different location, `mv /etc/localtime /etc/localtime-backup`.
  5. Create a symbolic link from the appropiate timezone to /etc/localtime. Example: `ln -s /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime`.
  6. If you have the utility rdate, update the current system time by executing `/usr/bin/rdate -s time.nist.gov`.
  7. Set the ZONE entry in the file /etc/sysconfig/clock file (e.g. “America/Los_Angeles”)
  8. Set the hardware clock by executing: ` /sbin/hwclock –systohc`
