timedatectl 是 RHEL7 上的一项新功能。它可用于查询和更改系统时钟及其设置。
按照以下步骤将时区更改为中国。（以root用户身份执行以下命令）。
1.使用以下命令列出所有可用的时区。你将使用此命令获得一长串时区。
# timedatectl list-timezones Africa/Abidjan Africa/Accra Africa/Addis_Ababa Africa/Algiers ....
2.找到中国时区中所需的正确时区并设置特定时区。有一个名为 tzselect 的命令可以帮助您找到所需的时区。例如，要在中国查找时区，请按如下所示使用它：
# tzselect Please identify a location so that time zone rules can be set correctly. Please select a continent or ocean. 1) Africa 2) Americas 3) Antarctica 4) Arctic Ocean 5) Asia 6) Atlantic Ocean 7) Australia 8) Europe 9) Indian Ocean 10) Pacific Ocean 11) none - I want to specify the time zone using the Posix TZ format. #? 5 Please select a country. 1) Afghanistan 18) Israel 35) Palestine 2) Armenia 19) Japan 36) Philippines 3) Azerbaijan 20) Jordan 37) Qatar 4) Bahrain 21) Kazakhstan 38) Russia 5) Bangladesh 22) Korea (North) 39) Saudi Arabia 6) Bhutan 23) Korea (South) 40) Singapore 7) Brunei 24) Kuwait 41) Sri Lanka 8) Cambodia 25) Kyrgyzstan 42) Syria 9) China 26) Laos 43) Taiwan 10) Cyprus 27) Lebanon 44) Tajikistan 11) East Timor 28) Macau 45) Thailand 12) Georgia 29) Malaysia 46) Turkmenistan 13) Hong Kong 30) Mongolia 47) United Arab Emirates 14) India 31) Myanmar (Burma) 48) Uzbekistan 15) Indonesia 32) Nepal 49) Vietnam 16) Iran 33) Oman 50) Yemen 17) Iraq 34) Pakistan #? 9
Please select one of the following time zone regions.
1) Beijing Time
2) Xinjiang Time
#? 1
The following information has been given:
China
Beijing Time
Therefore TZ=‘Asia/Shanghai‘ will be used.
Local time is now: Thu Aug 22 16:57:30 CST 2019.
Universal Time is now: Thu Aug 22 08:57:30 UTC 2019.
Is the above information OK?
1) Yes
2) No
#? 1
You can make this change permanent for yourself by appending the line
TZ=‘Asia/Shanghai‘; export TZ
to the file ‘.profile‘ in your home directory; then log out and log in again.
Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Shanghai
# timedatectl set-timezone Asia/Kolkata
3. 运行 “date” 命令查看时间是否正确
# date Thu Aug 22 17:04:39 CST 2019
您还可以使用 timedatectl status 命令检查详细状态。
# timedatectl status Local time: Thu 2019-08-22 17:05:14 CST Universal time: Thu 2019-08-22 09:05:14 UTC RTC time: Thu 2019-08-22 09:05:14 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: n/a
