Description:
I have read some online document saying that I can set the time_zone variable by running some scripts. However, the time_zone variable falls back to default after MySQL server restart.

How to repeat:
First, we the time_zone to GMT by doing this:

set global time_zone='+00:00';

To see the time_zone variable, I run this:

select @@global.time_zone;

It will say the time_zone is "+00:00", which is what I want. 

However, after restarting MySQL server, the time_zone falls back to "SYSTEM". 

So, is there any significant difference between global and session variables?
