Above is to show the system time, below is to show the hardware time; here because I am modified, it is just as fast, if not as fast, follow the following.

This is the year, month and day of the change system, and you can also change the hours and seconds. Same orders.

This is the time when it is directly updated to this time zone under the condition of having a network.

This is to adjust the hardware time to the same as the system time.

This is to write the date into the CMOS.

All right, it's done, and then you can check whether your hardware time and system time are the same.

Ps: the whole thing is to enter commands under root authority.
