Where it's felt important enough, or is accessible enough,
people are prepared, it seems, to do the necessary work.
Britain appears to lead the world in that respect. It
probably helps to be a small, civilized country. :)

On the subject of leap seconds, I think there's a point
that's missed on this Wiki page:
https://en.wikipedia.org/wiki/Greenwich_Time_Signal
where it says: "Until 1972, the pips were of equal length
and confusion arose as to which was the final pip, hence
the last pip is now of extended length."

My recollection is of listening to the first "leap pip"
on Radio4, which was the first time the final pip had
been made longer. (There had been discussions about
leap seconds on Radio4 in the lead up to the event.)

Cheers,
David.
