Thanks Les,

I've come up with a detailed agenda as to how I will be using that extra second.

If you have a short wave receiver, it is amusing to listen to WWV in
Colorado and WWVH in Hawaii for the additional second and I have
done this on occasion.

See

There has been some professional discussion going on for some time about whether
leap seconds in the future will be abandoned.

TAI, which is an atomic clock time, differs from UTC by the number of leap seconds
inserted since 1960 January 1.0, so come 11:00 AEDT tomorrow, TAI will be
34 seconds ahead of UTC.

For some astronomical calculations, this is significant difference and one can't
always blindly use UTC without taking the accumulated leap seconds into account.

Happy New Year!

Best Regards
