Linux Time Set

As a programmer, dealing with time is an integral part of many projects. Linux provides a convenient command-line tool to set the system date and time, known as date.

To set the system date and time in Linux, you can use the following command:

sudo date -s "2022-01-01 14:30:00"

This command sets the system time to January 1st, 2022 at 2:30 PM.

If you want to synchronize the system time with an NTP (Network Time Protocol) server, you can use the following command:

sudo ntpdate pool.ntp.org

This command synchronizes the system time with the NTP server pool.ntp.org.

You can also set the hardware clock (also known as the BIOS clock) using the hwclock command. To set the hardware clock to the system time, use the following command:

sudo hwclock --systohc

This command sets the hardware clock to the current system time.

In summary, Linux provides several command-line tools to set the system time and synchronize it with an NTP server or hardware clock. As a programmer, understanding how to work with these tools is essential for developing reliable and accurate software.
