I focused on the UT1, because UTC could _conceiveably_ have relevance,
whereas there is absolutely no way UT1 can come into play as a distinct
timescale from UTC.

Correct, but you don't use all of that for birthdays, because you
don't record the timezone of birth.

My son was born on march 31 in California on Mount Diablo Hospital.

But at the time it was April 1st in Denmark.

Yet his birthday is 31st of march, no matter where on the world he
choses to celebrate it.

Birthdays simply don't have timezone inforation attached to them,
end of story.

Consequently, if anybody claims that UT1 as distinct from UTC has
any relevance for birthcertificates, I want to see the proof, because
the claim is entirely nonsensical and counter intuitive in every
way.
