1.可以执行tzselect命令按提示更换时区，依次选择5-Asia，9-China，1-Beijing Time。
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: Wed May 30 10:04:16 CST 2018. Universal Time is now: Wed May 30 02:04:16 UTC 2018. 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
1.将TZ=’Asia/Shanghai’; export TZ这行添加到/etc/profile（所有用户生效）或者~/.bash_profile（当前用户生效）
2.退出重新登录即可，也可执行source /etc/profile或source ~/.bash_profile立即生效
3.这时候再执行date查看日期就可以发现时区改为北京时间啦。
