I think it would be useful to have a function which returns the time and duration of the next transition given time X and timezone Y (e.g., 2 AM Mar 30 -1 hour).

OK, that sounds like a good idea. I have just added a function tz_jump() to my proposal that I hope does what you want. It allows you to iterate through both leap seconds and timezone changes, perhaps even calendar exceptions. Please have a look at section 1.3.4 in http://www.cl.cam.ac.uk/~mgk25/c-time/ Markus -- Markus G.
