Daylight saving time...

I looked at the clock about half an hour ago and it said "Sun Nov 4, 1:37:16 AM".

I just looked at it again and now it says "Sun Nov 4, 1:07:37 AM".

At first I thought I must have read it wrong the first time, or I was so sleepy I was hallucinating (even though I'm not actually sleepy). And then I remembered Daylight Saving Time ends at 2:00 AM on November 4 this year.
