I am in New Zealand and have this problem as well.  We just changed back from DST on the weekend(coming into winter here), and I've had to change my time zone to show the correct time.  I usually have to adjust it several times a year depending on whether it is us in NZ changing, or the server chaning to/from DST.  At one stage I have to just have the wrong time cos there is no option to show the right time - hard to explain but NZ shows as GMT +12 hours, and with the inconsistencies with DST changing we are sometimes at GMT +13hrs, but there is no option to change to that.  I have gotten used to it in the 7 odd years I have been using this site, and just make sure I keep up with games.
