Aarrgghh!  The subject should read "seconds", of course (too much blood in 
my coffee stream).

I wrote a near-trivial "timestamp" command to make it easier to do time
arithmetic (handy for scheduling a doctor's appointment a 90-day medicine
supply from now).

TZ=udt timestamp

Not likely I'll live to see 2500000000. I surely won't live to see a
half-billion years.

I'm patiently waiting for another Gilded Age:

  % date -u `{hoc -e 'int(PHI * 1e9)'}
  Sat Apr 10 05:53:08 GMT 2021

Though I wish I was around for the Belle [Labs] Époque.

Cheers,
