ubuntu 和windows 7 时间相差几天怎么处理？

突然发现我的虚拟机里的时间和win7的时间相差几天，网上搜索的什么utc时间都没有用，经过不懈努力解决了，

具体如下：

1.添加dns

vi /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND — YOUR CHANGES WILL BE OVERWRITTEN nameserver 8.8.8.8 查询域名信息 nslookup time.stdtime.gov.tw Server: 8.8.8.8 Address: 8.8.8.8#53 Non-authoritative answer: Name: time.stdtime.gov.tw Address: 118.163.81.61

3.校准

ntpdate cn.pool.ntp.org 10 Mar 02:38:59 ntpdate[2053]: step time server 203.107.6.88 offset 468712.349299 sec

4.验证为UTC时间

date Tue Mar 10 02:39:21 UTC 2020

5.utc 改为cst

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: Sun Oct 28 11:12:54 CST 2018. Universal Time is now: Sun Oct 28 03:12:54 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

发现将 TZ=Asia/Shanghai 添加到./profile下没有用，

6.执行以下命令

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime echo Asia/Shanghai >/etc/timezone

7.source /etc/localtime

8.验证OK
