Why only one option for each GMT offset? I am in Israel, and our Daylight Savings Time start and end dates do not correspond to EET, which is the only choice I have for GMT+2.
Thus, right now, all times I see on my screen are one hour too late (we just officially started winter…)
Try moving to the next one along that’s closest, numerically, to your timezone. I’ll have the same problem shortly when NZ goes to Daylight Saving Time. This board’s timezone choice doesn’t go up that far (GMT +13).
