故障现象

系统日志时间晚了整整8个小时，比如现在是中午12点，日志时间为凌晨4点

date命令报错（Local time zone must be set--see zic manual page）

解决方案（失败）

修改/etc/profile
```
export TZ="Asia/Shanghai"
```
无效，date命令显示正常，但是放在脚本中的date命令依然报错，并且日志时间依然延后8小时

tzselect配置

#tzselect

11) none - I want to specify the time zone using the Posix TZ format.

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 Nov 2715:47:48 CST 2019.
Universal Time is now:    Wed Nov 2707:47:48 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
[root@compute-0-10: 2019年 11月 27日 星期三 07:47:59 Local time zone must be set--see zic manual page /root  3] 
#date
2019年 11月 27日 星期三 07:48:38 Local time zone must be set--see zic manual page

无效

/etc/localtime

rm -f /etc/localtime
cp  /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

依然没有什么鸟用

最后网上看了一篇文章大概是说可能是升级libc.so.6导致，尝试以下方法总算成功了

解决方案（成功！）

#ll /usr/local/glibc-2.14/etc/
总用量 8
-rw-r--r-- 1 root root 3694 7月  1709:50ld.so.cache
lrwxrwxrwx 1 root root   25 7月  1709:50 localtime -> ../share/zoneinfo/Factory
-rw-r--r-- 1 root root 1615 7月  1709:50 rpc
#cd /usr/local/glibc-2.14/etc/
#rm localtime 
rm：是否删除符号链接 "localtime"？y
#ln -s /usr/local/glibc-2.14/share/zoneinfo/Asia/Shanghai localtime
