West Africa Time
West Africa Time, or WAT, is a time zone used in west-central Africa. West Africa Time is one hour ahead of Coordinated Universal Time (UTC+01:00), which aligns it with Central European Time (CET) during winter, and Western European Summer Time (WEST) / British Summer Time (BST) during summer. As most of this time zone is in the tropical region, there is little change in day length throughout the year and therefore daylight saving time is not observed. West Africa Time is the time zone for the following countries:

 Algeria (as Central European Time)
 Angola
 Benin
 Cameroon
 Central African Republic
 Chad
 Democratic Republic of the Congo (western side only)
 Equatorial Guinea
 Gabon
 Morocco (as Central European Time)
 Niger
 Nigeria
 Republic of the Congo
 Tunisia (as Central European Time)
 Western SaharaCountries west of Benin (except Morocco and Western Sahara) are in the UTC±0 time zone. Civil time in most of those countries is defined with reference to Greenwich Mean Time (now an alias for UTC±0, rather than an independent reference).
