Namibia works on Central African Time (CAT),which is Greenwich Mean Time (GMT) + 2 hours. Namibia does not work on any seasonal time changes. Although we did in the past, this changed in 2019. Note however that if your tour takes you along the Caprivi and into Botswana, you may well need to note a change in time zones as some areas do still work on daylight savings time in the winter months between April to September.
