I am so thrilled! Daylight saving time got me to experience (kind of) the sleeping beauty problem first hand.
Last night we in Sweden changed our clocks back one hour at 03.00 to 02.00 and went from “summertime” to the dreaded “wintertime”. It’s dreaded because we know what follows with it, ice storms and polar bears in the streets…
Anyways, I woke up in the middle of the night and I reached for my phone to check what time it was. It was 02.50. Then it struck me. Am I experiencing the first 02.50 or the second 02.50 this night, i.e. have I first slept to 03, then the clock have changed back to 02 (which it automatically does on the phone) and then slept until 02.50 the new time or am I on the first 02.50 and in 10 minutes at 03 the clock will switchback to 02?
It was a very dizzying thought. I could not for my life say either or. There was nothing in the dark that could give me any indication weather I was experiencing the first or the second 02.50. Then with my thoughts spinning I slowly waited for the clock on my phone to turn 03. When it did, it did not go back to 02, I had experienced the second 02.50 that night.
