PlayOnLinux error on application when I change my timezone

Question

I have a game (scrolls.com) that I'm running under wine. Everything was OK, until I moved and changed my timezone.

Now, if I keep my old timezone it works. But if I change the timezone to something else, I get a black screen and the following error message:

I read that the issue is due to a mismatch between the timezone in the registry, and the one in the computer. Strangely I tried to reinstall using the new timezone, but the problem persists.

How can I update the registry inside wine? and preferable using PlayOnLinux would be better.

Edit. Moreover, it seems that the problem is only with my new timezone (Santiago) as others seem to work fine.

Answer 1

a) start wine with a different TZ

One solution would be to simply start wine with a different timezone each time (you probably want to update the shortcut in your start menu for example) using:

TZ=Europe/Berlin wine

b) change the TZ in wine

The registry of wine lies in ~/.wine in the files system.reg (=HKEY_LOCAL_MACHINE), user.reg (=HKEY_CURRENT_USER), userdef.reg (=HKEY_USERS) and is accessible by simply running regedit through wine (wine regedit).

The timezone key is in Local Machine -> SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones and can be set to any of the values that you see as directories at this place.
