Time change, new clock

Last night I was reading before going to bed. I looked at the clock and it was around 2 am. I did all the necessaries before going to bed and when I got there my new alarm clock said 3 am. I was surprised because I really thought it was 2 and how did it take me so long to get to bed? Oh, well, must have looked at the clock wrong. No big deal. Then this morning I realized it was the day for the time change and that my new alarm clock changes the time on its own! I need more clocks like that!
