This is correct, and this is how zic interprets it.

There are a few others; namely, America/Montreal, Asia/Amman, Asia/Gaza,
Asia/Hebron, and Europe/Helsinki.

On the contrary, 24:00 is meant to be quite *un*ambiguous. We can't stop
governments from ambiguously declaring that rules start "at midnight"
without specifying which one. But we can be clear, when representing those
rules, about which midnight we understand to be the correct one to use.
In some cases, that's simpler to express with 00:00; in others, with
24:00. Africa/Cairo's main (non-Ramadan) rules for the near future are
most succinctly expressed with one of each:
Rule Egypt 2014 max - Sep lastThu 24:00 0 -
Rule Egypt 2015 2019 - Apr lastFri 0:00s 1:00 S
Anyway, the use of 24:00 _seems_ to have broken the JodaTime library.
That may be, but if so, it's been broken for five years.
