Turn daylight saving off

[TimTDP]

I have a Nokia 920
My calendar appointments are suddenly 1 hour out!
I assume this is due to daylight saving?

How do I turn daylight saving off?

Time zone is set to UTC +2:00 Harare, Pretoria (I live in Cape Town)
Regional format is set to South Africa (English)
