In this issue, the editor will bring you about how to set the time and date in the CentOS 7 system. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Show current time zone

Use the following command:

The code is as follows:

~] $localectl status

System Locale: LANG=en_US.UTF-8

VC Keymap: us

X11 Layout: n/a

As you can see, in addition to the time zone information of the system, keyboard information and X11 layout information are also displayed

List all time zones

Display all English time zones with the following command

The code is as follows:

~] $localectl list-locales | grep en_

En_AG

En_AG.utf8

En_AU

En_AU.iso88591

En_AU.utf8

En_BW

En_BW.iso88591

En_BW.utf8

If you want to display it in Chinese, just change grep en to grep zh.

Set the local time zone

Use Root to execute the following command:

The code is as follows:

Localectl set-locale LANG=locale

Replace the final locale with a specific time zone, such as zh_CN.UTF-8.

Isn't that powerful.

Timedatectl

Let's solemnly introduce the timedatectl command ~

In previous versions of CentOS, time was set with a series of commands such as date, hwclock, etc., but CentOS 7 started with a unified command:

The code is as follows:

Timedatectl

This command is very powerful, starting with the direct use of some information that shows the current system time:

The code is as follows:

~] $timedatectl

Local time: Mon 2013-09-16 19:30:24 CEST

Universal time: Mon 2013-09-16 17:30:24 UTC

Timezone: Europe/Prague (CEST, + 0200)

NTP enabled: no

NTP synchronized: no

RTC in local TZ: no

DST active: yes

Last DST change: DST began at

Sun 2013-03-31 01:59:59 CET

Sun 2013-03-31 03:00:00 CEST

Next DST change: DST ends (the clock jumps one hour backwards) at

Sun 2013-10-27 02:59:59 CEST

Sun 2013-10-27 02:00:00 CET

Set the current date:

Using Root, execute the following command:

The code is as follows:

Timedatectl set-time YYYY-MM-DD

Set the current time:

You still need Root permission.

The code is as follows:

Timedatectl set-time HH:MM:SS

By default, the system uses UTC time, which can be turned on and off with the following command:

The code is as follows:

Timedatectl set-local-rtc boolean

Replacing boolean with yes means using local time, and replacing with no means UTC time.

Set any time zone

You can view all time zones with the following command:

The code is as follows:

Timedatectl list-timezones

Then set the time zone with the following command:

The code is as follows:

Timedatectl set-timezone time_zone

Of course, root authority is inevitable.

Synchronize with a remote NTP server

Timedatectl can also set whether or not to turn on the NTP option

The code is as follows:

Timedatectl set-ntp boolean
