Hiya,
I'm in the UK, it's summertime here, so I try to set my forum settings to GMT, with DST ticked.
However when I save this it always changes my time zone to GMT-1 (Azores).
If I try setting the time zone to GMT+1 (Berlin) with DTS ticked, it save fine.
It only seems to have a problem with GMT.
It's slightly irritating...
Ian.
