Let me be the first to say that the International Earth Rotation Service
has announced that there will be a Leap Second inserted at 23:59:59 UTC on
the 31st December, due to the earth slowly slowing down. It's fun to
listen to see how the time beeps handle it; will your GPS clock display
23:59:60, or will it go nuts like my last one did (I had to power cycle
the thing)?
My recording of the last one: horsfall.org/leapsecond.webm .

I told a coworker about leap seconds the other day, in the middle of
discussing software that doesn't understand 24:00:00 as a time of day.
For a while, I believe he thought that I was pulling a prank on him.

A year and half ago, a running Multics emulation (Multics, so slightly on
topic) was crashed by the leap second. An improbable race condition in a in
a messaging library used by the DPS8M emulator fired an assertion, bring
the whole thing down.
