Different event time when save to calendar

When anyone does a "Save To" iCal or other personal calendar, the event time changes and is not correct. I'm sure it's some easy setting somewhere. But where?

Nevermind. Found the problem and fixed it.

Great. Thanks Dan for confirming. If someone has same issue, go to System -> Global Configuration, look at Server tab, find the config option Server Time Zone, set it to your country timezone

After that, it will work as expected
