Because the zones are out of normal scope for the 22309583Sglebius# database, less effort is put into maintaining this file. Many of 23309583Sglebius# the zones were formerly in other source files, but were removed or 24309583Sglebius# replaced by links as their data entries were questionable and/or they 25309583Sglebius# differed from other zones only in pre-1970 time stamps. 26309583Sglebius 27309583Sglebius# Unless otherwise specified, the source for data through 1990 is: 28309583Sglebius# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), 29309583Sglebius# San Diego: ACS Publications, Inc.

Keep this in mind when you ask the time in Amharic. 48309583Sglebius# 49309583Sglebius# Shanks & Pottenger write that Ethiopia had six narrowly-spaced time 50309583Sglebius# zones between 1870 and 1890, that they merged to 38E50 (2:35:20) in 51309583Sglebius# 1890, and that they switched to 3:00 on 1936-05-05.
