There are a few reasons why your computer’s time might be wrong. It could be because your computer’s BIOS is not set correctly, or because your computer is not syncing its time with an NTP server. To fix this, you can try setting your computer’s BIOS to the correct time, or syncing your computer’s time with an NTP server.

To set your computer’s BIOS to the correct time, you will need to enter the BIOS setup utility. This is usually done by pressing a key during bootup, such as F12 or Esc. Once in the BIOS setup utility, look for the “Date” and “Time” settings. Set the date and time to the correct values, then save your changes and exit.

How to Sync time with  ntp service in Linux

The ntp service is a daemon that runs on Linux systems and synchronizes the system time with an NTP server. This ensures that the system time is accurate even when the system is turned off. To use the ntp service, you will need to install the ntp package. Once installed, you can start the service by running “sudo service ntp start”. To configure the ntp service, you can edit the “/etc/ntp.conf” file.

To check if your computer’s NTP service is active, you can use the “timedatectl” command. For example, to check if the NTP service is active, you would type the following command: sudo timedatectl status | grep -i ntp

If the NTP service is active, you will see a line that says “NTP synchronized: yes”. If the NTP service is not active, you will see a line that says “NTP synchronized: no”.

To manually sync your computer’s time with an NTP server, you can use the “ntpdate” command. For example, to sync your computer’s time with the NTP server pool.ntp.org, you would type the following command: sudo ntpdate pool.ntp.org
