Use only Ascii letters, digits, `.', -# `-' and `_'. Do not exceed 14 characters or start with `-'. -# E.g. prefer `Brunei' to `Bandar_Seri_Begawan'. -# Include at least one location per time zone rule set per country. -# One such location is enough. -# If all the clocks in a country's region have agreed since 1970, -# don't bother to include more than one location -# even if subregions' clocks disagreed before 1970. -# Otherwise these tables would become annoyingly large. -# If a name is ambiguous, use a less ambiguous alternative; -# e.g. many cities are named San Jose and Georgetown, so -# prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'. -# Keep locations compact. Use cities or small islands, not countries -# or regions, so that any future time zone changes do not split -# locations into different time zones. E.g. prefer `Paris' -# to `France', since France has had multiple time zones. -# Use traditional English spelling, e.g. prefer `Rome' to `Roma', and -# prefer `Athens' to the true name (which uses Greek letters). -# The Posix file name restrictions encourage this rule. -# Use the most populous among locations in a country's time zone, -# e.g. prefer `Shanghai' to `Beijing'. Among locations with -# similar populations, pick the best-known location, -# e.g. prefer `Rome' to `Milan'. -# Use the singular form, e.g. prefer `Canary' to `Canaries'. -# Omit common suffixes like `_Islands' and `_City', unless that -# would lead to ambiguity. E.g. prefer `Cayman' to -# `Cayman_Islands' and `Guatemala' to `Guatemala_City', -# but prefer `Mexico_City' to `Mexico' because the country -# of Mexico has several time zones. -# Use `_' to represent a space. -# Omit `.' from abbreviations in names, e.g. prefer `St_Helena' -# to `St._Helena'. -# -# 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.
