I don't know about other countries, but tonight in the US except for a few exceptions is the weekend to set the clocks ahead one hour. Just a reminder.
One of the managers at Walgreens set the clock on the lights a week early, so they'd dim at 9:15 instead of 10:15 all week when we close at 10. Makes it fun to see customer's reactions, though.
I forgot to set only two clocks; my alarm clock and my wristwatch. Good thing I usually get to work 45 minutes early-between that and driving a little faster than usual, it saved me from being late today.
