Steve,
And UTC has failed miserably. POSIX says UTC has no leaps.
Google says UTC has occasional days with stretches of seconds which
are of varying lengths. De facto, there is no single UTC time scale.
Right! And many more examples of UTC fails -- the RTC of any unix computer. Any
windows
Overall he seems to make a good philosophical argument why solar time is
good for humans. But his conclusion seems confused.
... let the airlines and the Internet companies use TAI.
Ah, the airlines already use GPS (TAI-like) for navigation, and local
civil time for scheduling, while the
You are correct to not call biological cycles clocks. Doing so is one
of my pet peeves, and I've recently published an article castigating the
psychophysics folks for doing so. The reference to that is:

Alternatives to the
My post was not to suggest that circadian cycles will be affected by leap
seconds or their absence as much as to point out that Mr. Folkman's
argument is a better argument against mean time than an argument in favor
of keeping the leap second.
Getting rid of the leap second will probably have no

Steve,
POSIX does not say that UTC has no leaps, it says that POSIX has no UTC
(despite the superficial similarity).

In other words, let them simply stop adjusting for for leap seconds.
Let the atomic clocks become progressively more wrong.
Whoa! Hold the phone! What do you mean? Adjust TAI's frequency to
match Earth?!?
No, he's clearly proposing to leave TAI exactly as it is, and just to

A couple more comments on your questions.
Many timekeeping systems seem to be designed for only indicating now
