Africa uses 6 time zones:
Cape Verde Time ( GMT-1 )
Greenwich Mean Time ( GMT )
West Africa Time ( GMT+1 )
Central Africa Time ( GMT+2 )
East Africa Time ( GMT+3 )
Mauritius Time & Seychelles Time ( GMT+4 )
Most of Africa spans the Equator so daylight hours don't vary that much across the year and Daylight Saving Time (DST) is not used in most of Africa.
