(for example, to have your computer automatically synchronize its clock with
official time servers on the Internet), you can do so.
Changing the Time and Date
Using Ubuntu’s graphical tool is the simplest way to set your system date and
time and the most obvious for a desktop user. From the Settings window
select Details and then select Date & Time to make changes. You can
manually set the date and time in the GUI or have your computer obtain
updated date and time information via the Internet.

Use the date command to display or set your Linux system time. This
command requires you to use a specific sequence of numbers to represent the
desired date and time. To see your Linux system’s idea of the current date and

a.m.), use a command line with the month, day, hour, minute, and year, like
so:

hardware times. To see your hardware time and date, use hwclock with the
—show option, like so:

Use hwclock with its —set and —date options to manually set the
hardware clock, as follows:
