Zone terminology

Guy Harris 2013-09-18 23:37:48 http://mm.icann.org/pipermail/tz/2013-September/020284.html

So I prefer terms such as "tzdb zone" to refer to those things that have tzids. I'm not wedded to *that* term, but there should be *some* term other than "time zone" for that.

The tzdb currently does not have a concept of "time zone" in the sense of a region with a specified base time offset; are you suggesting that it add one?

-AQ     -9000+00000     Antarctica/South_Pole   Amundsen-Scott Station, South Pole
+AQ     -7750+16636     Pacific/Auckland        McMurdo, South Pole, Scott (New Zealand time)

So Pacific/Auckland now has two pairs of coordinates, the new AQ-one and the old NZ-one.

NZ	-3652+17446	Pacific/Auckland	most locations
