The math is good anywhere.  You may not like the interpretation of the
results, though.

Which doesn't tell me what UT is.

For those that want piles of details; I suppose.  I was wondering which
version of UT you were referring to.

At any rate, nothing will be done until after the next release of
Emacs.  Then I'll check to see how other programs handle DST.  Since the
original bug report didn't report a bug, I'll close this report.
