A little note for fun...

- I forgot to set right my watch on British Summer Time; I was nearly late for school!
- Serves you right! So maybe you’ll understand it’s no use protesting against time change!
- British Summer Time made me get a bad report.
- What do you mean?
- The teacher asked at what time the sun was the highest; I answered two o’clock and six minutes.
- I see, there are two hours more than solar time; you must have answered two o’clock.
- No, the teacher said noon.
- I see… but, incidentally, why six minutes?
- The nutation.
- The… what?
- The nutation; it’s another difference. We are at Brest, and today is the first of June.
- What kind of difference is it? Who’s going to know that?
- That was the teacher’s lesson three months ago.
