Tanzania is + 3 GMT
This means the local time is three hours ahead of London, eight hours ahead of New York and eleven hours ahead of Los Angeles. Tanzania does not observe daylight saving time so the difference changes by one hour in the European and North American summer.
The best thing you can bring on safari is a good attitude. Remember that you’re experiencing a new and different culture and that Tanzania is a developing nation with limited infrastructure. Things will not be the same as at home and that’s part of the joy of travel.
