I have updated the efele.net/tz maps (http://efele.net/maps/tz/) to be in sync with TZ 2015g. The new zones:
It's great to see this updated. A few comments on the data: (1) There are a few shapes in the maps that correspond to zones that are now links. (These are at least America/Coral_Harbour, America/Montreal, Asia/Chongqing, Asia/Harbin, Asia/Kashgar, and Pacific/Yap. Those are the zones that are now links that are no longer listed in zone.tab; many other links are still listed in zone.tab, so I didn't catch those.) It's not clear to me if it is intentional to retain these as distinct shapes given that you already have the map data for them, or whether it would be better to merge them into the shapes for the zones that they are now linked to. (2) I noticed that the map uses the Sudanese claim for the border between Egypt and Sudan. This surprised me a little bit given that it was my understanding that Egypt had de-facto control of the one of the three deviations between the claims that is populated: https://en.wikipedia.org/wiki/Hala'ib_Triangle . Then again, my only source here is Wikipedia, so there may well be more authoritative information about what timezone is used in the Hala'ib Triangle. (3) When overlaying on other maps, I notice that the edges of the Aral sea are rather out-of-date. (I've been playing with using the data to draw a "live" timezone map on the Web, i.e., a map of the world with time zone lines as they are at a particular time, including summer time shifts, but with boundaries shown only where there are actual time changes at that time. I'm not happy with what I have yet (mainly because it's still rather slow), though the source is at https://github.com/dbaron/timezone-map .) -David -- π L.
