Date and Time in CentOS / RHEL 7

timedatectl

To display the current date and time, you can use timedatectl or as other Linux and Unix systems use the standard date command: 

$ date
$ timedatectl

To change the current date, simply enter the following command as root: 

# timedatectl set-time 2013-06-02

To synchronize the system time with an NTP server:

# timedatectl set-ntp true

date command 

As I mentioned before, date command also works in CentOS / RHEL:

$ date +"%m-%d-%Y %H:%M"

To change the current time:

# date +%T --set 13:19:00

hwclock

hwclock is another tool which shows and sets the motherboard time and date:

# hwclock
