Well, I didn't understand until late in the discussion that it's unusual
for people to want their human-readable time to be (currently) 22
seconds off from "civil" time.  I thought it was normal to do that among
those who are trying keep their system clocks in sync with TAI.

But once I realized that I am an outlier in wanting to do this with my
human-readable time, I decided to remain so.  That's the "whimsical"
part.

But I'm sorry if I have wasted bandwidth in trying to understand all
of this.
