# European-style abbreviations are commonly used along the Mediterranean.
# For sub-Saharan Africa abbreviations were less standardized.
# Previous editions of this database used WAT, CAT, SAT, and EAT
# for +0:00 through +3:00, respectively,
# but Mark R V Murray reports that
# 'SAST' is the official abbreviation for +2:00 in the country of South Africa,
# 'CAT' is commonly used for +2:00 in countries north of South Africa, and
# 'WAT' is probably the best name for +1:00, as the common phrase for
# for UT +00 through +03, respectively,
# but in 1997 Mark R V Murray reported that
# 'SAST' is the official abbreviation for +02 in the country of South Africa,
# 'CAT' is commonly used for +02 in countries north of South Africa, and
# 'WAT' is probably the best name for +01, as the common phrase for
# the area that includes Nigeria is "West Africa".
# He has heard of "Western Sahara Time" for +0:00 but can find no reference.
#
# To make things confusing, 'WAT' seems to have been used for -1:00 long ago;
# I'd guess that this was because people needed _some_ name for -1:00,
# and at the time, far west Africa was the only major land area in -1:00.
# This usage is now obsolete, as the last use of -1:00 on the African
# mainland seems to have been 1976 in Western Sahara.
#
# To summarize, the following abbreviations seem to have some currency:
# -1:00 WAT West Africa Time (no longer used)
# 0:00 GMT Greenwich Mean Time
# 2:00 CAT Central Africa Time
# 2:00 SAST South Africa Standard Time
# and Murray suggests the following abbreviation:
# 1:00 WAT West Africa Time
# I realize that this leads to 'WAT' being used for both -1:00 and 1:00
# for times before 1976, but this is the best I can think of
# until we get more information.
# To summarize, the following abbreviations seemed to have some currency:
# +00 GMT Greenwich Mean Time
# +02 CAT Central Africa Time
# +02 SAST South Africa Standard Time
# and Murray suggested the following abbreviation:
# +01 WAT West Africa Time
# Murray's suggestion seems to have caught on in news reports and the like.
# I vaguely recall 'WAT' also being used for -01 in the past but
# cannot now come up with solid citations.
#
# I invented the following abbreviations; corrections are welcome!
# 2:00 WAST West Africa Summer Time
# 2:30 BEAT British East Africa Time (no longer used)
# 2:45 BEAUT British East Africa Unified Time (no longer used)
# 3:00 CAST Central Africa Summer Time (no longer used)
# 3:00 SAST South Africa Summer Time (no longer used)
# 3:00 EAT East Africa Time
# +02 WAST West Africa Summer Time
# +03 CAST Central Africa Summer Time (no longer used)
# +03 SAST South Africa Summer Time (no longer used)
# +03 EAT East Africa Time
# 'EAT' also seems to have caught on; the others are rare but are paired

# established DST from 1992-11-28 to 1993-02-05; it does not give transition
# times. The people called it "hora de Sixto" ("Sixto hour"). The change did
# not go over well; a popular song "Qué hora es" by Jaime Guevara had lyrics
# that included "Amanecía en mitad de la noche, los guaguas iban a clase sin
# sol" ("It was dawning in the middle of the night, the buses went to class
# without sun"). Although Ballén's campaign slogan was "Ni un paso atrás"
# (Not one step back), the clocks went back in 1993 and the experiment was not

# European-style abbreviations are commonly used along the Mediterranean.
# For sub-Saharan Africa abbreviations were less standardized.
# Previous editions of this database used WAT, CAT, SAT, and EAT
# for +0:00 through +3:00, respectively,
# but Mark R V Murray reports that
# 'SAST' is the official abbreviation for +2:00 in the country of South Africa,
# 'CAT' is commonly used for +2:00 in countries north of South Africa, and
# 'WAT' is probably the best name for +1:00, as the common phrase for
# for UT +00 through +03, respectively,
# but in 1997 Mark R V Murray reported that
# 'SAST' is the official abbreviation for +02 in the country of South Africa,
# 'CAT' is commonly used for +02 in countries north of South Africa, and
# 'WAT' is probably the best name for +01, as the common phrase for
# the area that includes Nigeria is "West Africa".
# He has heard of "Western Sahara Time" for +0:00 but can find no reference.
#
# To make things confusing, 'WAT' seems to have been used for -1:00 long ago;
# I'd guess that this was because people needed _some_ name for -1:00,
# and at the time, far west Africa was the only major land area in -1:00.
# This usage is now obsolete, as the last use of -1:00 on the African
# mainland seems to have been 1976 in Western Sahara.
#
# To summarize, the following abbreviations seem to have some currency:
# -1:00 WAT West Africa Time (no longer used)
# 0:00 GMT Greenwich Mean Time
# 2:00 CAT Central Africa Time
# 2:00 SAST South Africa Standard Time
# and Murray suggests the following abbreviation:
# 1:00 WAT West Africa Time
# I realize that this leads to 'WAT' being used for both -1:00 and 1:00
# for times before 1976, but this is the best I can think of
# until we get more information.
# To summarize, the following abbreviations seemed to have some currency:
# +00 GMT Greenwich Mean Time
# +02 CAT Central Africa Time
# +02 SAST South Africa Standard Time
# and Murray suggested the following abbreviation:
# +01 WAT West Africa Time
# Murray's suggestion seems to have caught on in news reports and the like.
# I vaguely recall 'WAT' also being used for -01 in the past but
# cannot now come up with solid citations.
#
# I invented the following abbreviations; corrections are welcome!
# 2:00 WAST West Africa Summer Time
# 2:30 BEAT British East Africa Time (no longer used)
# 2:45 BEAUT British East Africa Unified Time (no longer used)
# 3:00 CAST Central Africa Summer Time (no longer used)

# The other three time zones are called "Brasília time "minus one" or

# This says President Sixto Durán Ballén signed decree No. 285, which
# established DST from 1992-11-28 to 1993-02-05; it does not give transition
# times. The people called it "hora de Sixto" ("Sixto hour"). The change did
# not go over well; a popular song "Qué hora es" by Jaime Guevara had lyrics
# that included "Amanecía en mitad de la noche, los guaguas iban a clase sin
# sol" ("It was dawning in the middle of the night, the buses went to class
# without sun"). Although Ballén's campaign slogan was "Ni un paso atrás"
# (Not one step back), the clocks went back in 1993 and the experiment was not
# repeated. For now, assume transitions were at 00:00 local time country-wide.
