Linux时区设置

Linux 设置服务器时区 UTC 0区

Linux服务器建议使用UTC 0区且没有夏时令，Atlantic/Reykjavik正好符合，这样各个程序都比较简单，时间不用算来算去的。

“夏时令”也会影响时间的换算，wiki上有讲解。

sudo tzselect
 6) Atlantic Ocean
6
5) Iceland
5
You can make this change permanent for yourself by appending the line
	TZ='Atlantic/Reykjavik'; 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:
Atlantic/Reykjavik
