-# From Paul Eggert (2014-07-31):
-# Like the Swahili of Kenya and Tanzania, many Ethiopians keep a

-# 02:00 or 14:00.  Keep this in mind when you ask the time in Amharic.

-# Shanks & Pottenger write that Ethiopia had six narrowly-spaced time
-# zones between 1870 and 1890, that they merged to 38E50 (2:35:20) in
-# 1890, and that they switched to 3:00 on 1936-05-05.  Perhaps 38E50
