Chapter 17. Setting Time and Date in Red Hat Enterprise Linux 7

The section contains how to set time and date in Red Hat Enterprise Linux 7:

The system time is always kept in Coordinated Universal Time (UTC) and converted in applications to local time as needed. Local time is the actual time in your current time zone, taking into account daylight saving time (DST).

The timedatectl utility is distributed as part of the systemd system and service manager and allows you to review and change the configuration of the system clock.

timedatectl set-time HH:MM:SS

Replace HH with an hour, MM with a minute, and SS with a second, all typed in two-digit form.

timedatectl set-time YYYY-MM-DD

Replace YYYY with a four-digit year, MM with a two-digit month, and DD with a two-digit day of the month.

The time change is audited by the operating system. For more information, see Auditing Time Change Events.
