5 Jan 5.2 minutes
6 Jan 5.7 minutes

30 seconds in a day..

The total variation over the year is +/- 15 minutes, but the derivative
is a lot bigger at some times of the year (now)
_______________________________________________


Higher than I expected from a quick look at the graph.  I had 17 minutes 
total variation in 6 months in my mind!

Mind you, some figure in that table loom doubtful - Oct 01, 07, 13 - unless 
they are deliberately (and confusingly) missing out the "-" signs!

Thanks.
David
