Looking at the source code of "calendar-next-time-zone-transition", it looks very error prone to me. Am I reading the comments right? It initializes a binary search with the results of a heuristic?
Yes. It's a heuristic that should work with all real-world time zone histories (including all time zone histories in the tz database). It won't work in general, though.
Thanks! That's what I expected.
zdump uses a similar heuristic, if memory serves.
I suppose magic doesn't exist after all... Simon -- DTN made easy, lean, and smart --> http://postellation.viagenie.ca NAT64/DNS64 open-source --> http://ecdysis.viagenie.ca STUN/TURN server --> http://numb.viagenie.ca
