The timedatectl command allows you to query and change the configuration of the system clock and its settings, you can use this command to set or change the current date, time and timezone or enable automatic system clock synchronization with a remote NTP server.In this tutorial, am going to take you through the ways you can manage time on your Linux system by setting the date, time, timezone and synchronize time with NTP from the terminal using new timedatectl command.Locations are identified by continent or ocean and then by the name of the location, which is typically the largest city within the region.For example, America/New_York represents most of the US eastern time zone; America/Phoenix represents most of Arizona, which uses mountain time without daylight saving time (DST); America/Detroit represents most of Michigan, which uses eastern time but with different DST rules in 1975; and other entries represent smaller regions like Starke County, Indiana, which switched from central to eastern time in 1991 and switched back in 2006.Sometimes we forgot to set timezone properly for newly installed system or sometimes we need to change timezone of systems for various testing etc.

You can set the date and time on your system, using the timedatectl command as follows: To set time only, we can use set-time switch along the format of time in HH: MM: SS (Hour, Minute and Seconds).

The timedatectl command is a new utility for RHEL/Cent OS 7 and Fedora 21 based distributions, which comes as a part of systemd system and service manager, a replacement for old traditional date command used in sysvinit daemon based Linux distributions.

In Debian releases Etch and later, /etc/localtime is a copy of the original data file.

Check the contents of /etc/timezone to see the name of the timezone.

If you're running on Open VZ or Virtuozzo, ask your administrator to change the clock for you as that is controlled by your host.
