BST to SAST: convert British Time to South Africa Standard Time

In January, SAST is 2 hours ahead of BST. In July it is 1 hour ahead of. The gap moves because the two regions handle daylight saving differently.

The United Kingdom uses GMT in winter and BST (British Summer Time) in summer. BST also abbreviates Bangladesh Standard Time (UTC+6).
