In my ini file I have following time-zone default value: (In Workbench the correct values are also shown.)

    innodb = ON
    default-time-zone = '+00:00'

When I restart the server I always get 'SYSTEM' when I execute following query: 

    SELECT @@GLOBAL.time_zone, @@SESSION.time_zone;

From my application Dates are not saved in my system timezone and not in UTC.


I manually have to call at start:

    SET GLOBAL time_zone = '+00:00';
    SET SESSION time_zone = '+00:00';

How to repeat:
Use INNODB engine.

Set in workbench or ini file default time-zone to other then system timezone.

Check with query time_zone.

The DateTime column i observed was not setted by application but by default value, so this bug is not related to any client application.

In folder 'Program Data' there really is no 'default-time-zone' setting in 'my.ini' file. 

I know 'Program Data' has precedence over other folders, but

Workbench is instructed to use the 'my.ini' from 'Program Files' and settings are shown correctly in workbench.
