ubuntu 和windows 7 时间相差几天怎么处理？

Posted 2021-03-06 拙园

 

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

2. 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
