How do you modify the date and time in Linux?

In Linux, you can use the following command to modify the date and time:

1. The date command: used to display or set the system’s date and time.
2. Display the current date and time: date
3. Set the date and time format: date +%Y%m%d -s “20221231” (Set the date to December 31st, 2022)
4. Set the time format: date +%T -s “12:34:56” (Set the time to 12:34:56)
5. Set the date and time: date -s “2022-12-31 12:34:56”
6. hwclock command: used to manage the hardware clock.
7. Display hardware clock time: hwclock
8. Synchronize the hardware clock time with the system time: hwclock –systohc.
9. Set the hardware clock time to a specific date and time: hwclock –set –date “2022-12-31 12:34:56”

It should be noted that modifying the date and time usually requires root permissions.

Furthermore, you can manage the system’s time and timezone using the timedatectl command, including changing the date, time, and timezone.

I hope this helps you!
