 #	Omit `.' from abbreviations in names, e.g. prefer `St_Helena'
 #		to `St._Helena'.
 #
-# We typically use traditional English time zone abbreviations,
-# and assume that applications translate them to other languages
-# as part of the normal localization process.
+# For time zone abbreviations like `EST' I used the following rules,
+# in decreasing order of importance:
+#
+#	Use abbreviations that consist of 3 or more upper-case Ascii letters,
+#		except use "___" for locations while uninhabited.
+#		Posix.1 requires at least 3 characters, and the restriction to
+#		upper-case Ascii letters follows most traditions.
+#		Previous editions of this database also used characters like
+#		' ' and '?', but these characters have a special meaning to
+#		the shell and cause commands like
+#			set `date`
+#		to have unexpected effects.  In theory, the character set could
+#		be !%./@A-Z^_a-z{}, but these tables use only upper-case
+#		Ascii letters (and "___").
+#	Use abbreviations that are in common use among English-speakers,
+#		e.g. `EST' for Eastern Standard Time in North America.
+#		We assume that applications translate them to other languages
+#		as part of the normal localization process; for example,
+#		a French application might translate `EST' to `HNE'.
+#	For zones whose times are taken from a city's longitude, use the
+#		traditional xMT notation, e.g. `PMT' for Paris Mean Time.
+#		The only name like this in current use is `GMT'.
+#	If there is no common English abbreviation, abbreviate the English
+#		translation of the usual phrase used by native speakers.
+#		If this is not available or is a phrase mentioning the country
+#		(e.g. ``Cape Verde Time''), then:
+#
+#		When a country has a single or principal time zone region,
+#			append `T' to the country's ISO	code, e.g. `CVT' for
+#			Cape Verde Time.  For summer time append `ST';
+#			for double summer time append `DST'; etc.
+#		When a country has multiple time zones, take the first three
+#			letters of an English place name identifying each zone
+#			and then append `T', `ST', etc. as before;
+#			e.g. `MOSST' for MOScow Summer Time.
 #
-# I made up the following time zone abbreviations; corrections are welcome!
+#
+# For Africa I invented the following time zone abbreviations.
 #		LMT	Local Mean Time
-#	-2:00	CVT	Cape Verde Time (no longer used)

-#	 4:00	SMT	Seychelles and Mascarene Time
 # The final `T' is replaced by `ST' for summer time, e.g. `SAST'.
