Sorry - not enough coffee...

The next version will be draft-touch-art-time, keeping with the
convention that also includes the intended WG of interest...

I tried to indicate that in the abstract/intro.

It originated in response to two different threads on "hey, the IETF
should standardize some new time scale" - one to be purely monotonic and
the other to standardize Google-like leapsecond smear.

The point of the doc is to encourage people to use existing solutions
and not believe there's a shortcut that gets around needing to know/deal
with leap seconds, time zones, and coordination.

Yeah - that's intended to be background.

I'm open to suggestions on how far back to pull that background.

The reason for including it is to have the doc be somewhat
self-contained in justifying the recommendations.
