To change the current time, run the following command as root:

date +%T -s HH:MM:SS

…where HH stands for an hour, MM is a minute, and SS is a second, all typed in a two-digit form. If your system clock is set to use UTC (Coordinated Universal Time), also add the following option:

date +%T -s HH:MM:SS -u

For instance, to set the system clock to 11:26 PM using the UTC, type:

~]# date +%T -s 23:26:00 -u

You can verify the current settings by running date without any additional argument.
