I'll admit there were parts of me that really wanted to find some reason to
write 2024 Feb 29 24:00.  ;)

But, to me, the text of the decree clearly referred to 2024 Mar  1  0:00
or, as your translation puts it, "on the night of February 29, 2024 to
March 1, 2024 (at 00:00 hours)".

Most here would almost definitely have written this decree with effect from
24:00 on 29 February, to avoid confusion that any part of 1 March is
entered before the 23:xx hour is repeated a second time.  But the writers
of this decree chose to say 00:00, even though that's technically on 1
March, possibly figuring that specifying "midnight between two dates" would
be clearer to the public than saying "24:00" could be.

Fortunately the two approaches are equivalent as far as tzdb is
concerned, so we can choose to follow the text.
