Time zone names

The tz database says that Johnston Atoll is on Hawaiian Standard Time. Midway time was called Nome Standard Time until 1967-04, Bering Standard Time from then until 1983-11-30, and Samoa Standard Time since then. For technical purposes, the tz database assigns the names Pacific/Johnston, Pacific/Midway, and Pacific/Wake to those islands' time zones.
