 # Time in Saudi Arabia and other countries in the Arabian peninsula was not
-# standardized until relatively recently; we don't know when, and possibly it
+# standardized until 1968 or so; we don't know exactly when, and possibly it
 # has never been made official.  Richard P Hunt, in "Islam city yielding to
 # modern times", New York Times (1961-04-09), p 20, wrote that only airlines
 # observed standard time, and that people in Jeddah mostly observed quasi-solar
 # time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
 # o'clock for "Arab" time).
 #
+# Timekeeping differed depending on who you were and which part of Saudi
+# Arabia you were in.  In 1969, Elias Antar wrote that although a common
+# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset -
+# which meant that the time on one side of a mountain could differ greatly from
+# the time on the other side - many foreigners set their watches to 6pm
+# instead, while airlines instead used UTC +03 (except in Dhahran, where they
+# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line
+# Company used Aramco time in eastern Saudi Arabia and airline time in western.
+# (The American Military Aid Advisory Group used plain UTC.)  Antar writes,
+# "A man named Higgins, so the story goes, used to run a local power
+# station. One day, the whole thing became too much for Higgins and he
+# assembled his staff and laid down the law. 'I've had enough of this,' he
+# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is
+# going to run on Higgins Time.' And so, until last year, it did."  See:
+# Antar E. Dinner at When? Saudi Aramco World, 1969 March/April. 2-3.
+# http://archive.aramcoworld.com/issue/196902/dinner.at.when.htm

+# As is usual in tzdb, Ukrainian zones use the most common English spellings.
+# For example, tzdb uses Europe/Kiev, as "Kiev" is the most common spelling in

+# transliteration of the Ukrainian "Київ".  This is similar to tzdb's use of
+# Europe/Prague, which is certainly wrong as a transliteration of the Czech
+# "Praha".  ("Kiev" came from old Slavic via Russian to English, and "Prague"
+# came from old Slavic via French to English, so the two cases have something
+# in common.)  Admittedly English-language spelling of Ukrainian names is
+# controversial, and some day "Kyiv" may become substantially more popular in
+# English; in the meantime, stick with the traditional English "Kiev" as that
+# means less disruption for our users.
+#
+# Anyway, none of the common English-language spellings (Kiev, Kyiv, Kieff,
+# Kijeff, Kijev, Kiyef, Kiyeff) do justice to the common pronunciation in
+# Ukrainian, namely [ˈkɪjiu̯] (IPA).  This pronunciation has nothing like an
+# English "v" or "f", and instead trails off with what an English-speaker

 # Time in Saudi Arabia and other countries in the Arabian peninsula was not
-# standardized until relatively recently; we don't know when, and possibly it
+# standardized until 1968 or so; we don't know exactly when, and possibly it
 # has never been made official.  Richard P Hunt, in "Islam city yielding to
 # modern times", New York Times (1961-04-09), p 20, wrote that only airlines
 # observed standard time, and that people in Jeddah mostly observed quasi-solar
 # time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
 # o'clock for "Arab" time).
 #
+# Timekeeping differed depending on who you were and which part of Saudi
+# Arabia you were in.  In 1969, Elias Antar wrote that although a common
+# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset -
+# which meant that the time on one side of a mountain could differ greatly from
+# the time on the other side - many foreigners set their watches to 6pm
+# instead, while airlines instead used UTC +03 (except in Dhahran, where they
+# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line
+# Company used Aramco time in eastern Saudi Arabia and airline time in western.
+# (The American Military Aid Advisory Group used plain UTC.)  Antar writes,
+# "A man named Higgins, so the story goes, used to run a local power
+# station. One day, the whole thing became too much for Higgins and he
+# assembled his staff and laid down the law. 'I've had enough of this,' he
+# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is
+# going to run on Higgins Time.' And so, until last year, it did."  See:
+# Antar E. Dinner at When? Saudi Aramco World, 1969 March/April. 2-3.

+# means less disruption for our users.

+# Anyway, none of the common English-language spellings (Kiev, Kyiv, Kieff,

+# Ukrainian, namely [ˈkɪjiu̯] (IPA).  This pronunciation has nothing like an
