This article will explain in detail how to permanently modify the system time in CentOS. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Using Centos, when you encounter a local time mismatch, just hit the command: date-s "2017-01-05 10:15:15" is effective immediately, but after reboot, the system time is still the same.

After looking up the information, make a summary.

My Centos is installed on a virtual machine. There are subsystem time and hardware time in the virtual machine. One of the changes is that it doesn't work, and you have to change both.

1.date {check the current local time}

2.hwclock-- show {time to view hardware}

3. If the time of the hardware does not match, modify the time of the hardware,

4.hwclock-- set-- date '014-12-15 15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-15-

5.hwclock-- hctosys {set system time and hardware time synchronization}

6.clock-w {Save clock}

7. Finally, after a quick restart of init 6, check to see if the system time is really effective! one
