I even
saw the "A leap second is coming!" part of the navigation message.

And has anyone told the people wo run Big Ben in London?

Why should they? Big Ben is the great bell in the clock tower of the
Houses of Parliament.

It is the people who run the clock itself who need to know, and I am
confident that they are well aware of the occurrence of Leap Seconds and
have adequate arrangements for knowing about them.

Damn and Blast Sirrah!
I'll get "My Man" to remove another fine coin of the Realm to reduce the
timewarp factor and add a Ha'penny to compensate for the bird **** on the
pendulum........
