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
Please identify a location so that time zone rules can be set correctly.
Please select a continent or ocean.
) Africa
) Americas
) Antarctica
) Arctic Ocean
) Asia
) Atlantic Ocean
) Australia
) Europe
) Indian Ocean
) Pacific Ocean
) none - I want to specify the time zone using the Posix TZ format.

#?
Please select one of the following time zone regions.
) Beijing Time
) Xinjiang Time
#? The following information has been given: China
Beijing Time Therefore TZ='Asia/Shanghai' will be used.
Local time is now: Wed Nov :: CST .
Universal Time is now: Wed Nov :: UTC .
Is the above information OK?
) Yes
) No
#? 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--: 2019年 11月 27日 星期三 :: Local time zone must be set--see zic manual page /root ]
#date
2019年 11月 27日 星期三 :: 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
-rw-r--r-- root root 7月 : ld.so.cache
lrwxrwxrwx root root 7月 : localtime -> ../share/zoneinfo/Factory
-rw-r--r-- root root 7月 : 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
