Hang on a sec! You were so close to a really could suggestion!
Why can't they say, the sever will be down from XXX to XXX, and put the times as chosen in our personal settings? I don't exactly know how to express what I'm saying, but we've all chosen a time that can be seen in the forum and other places. So is there any way that the listed time could update based on our personal preferences? That way
everyone would have the correct time listed and no one would have to do any math. The only mistake would be if someone had their time set incorrectly which would be their own fault.
Yeti, Chip or someone smarter than me

....would this be possible?
