Whenever it is 2:30 PM in England, the time in Sweden is 3:30 PM. However, when the time in England is UTC + 1 hour, they don't call it Central European Time; they call it British Summer Time.
2:30 PM GMT in England = 3:30 PM CET in Sweden, and
2:30 PM BST in England = 3:30 PM CEST in Sweden.
CET +01:00 ; 1 hour ahead of London.
Yes. London has GMT (Greenwich Mean Time), Vienna has CET (Central European Time). The resulting time difference is one hour.

CET is Central European Time, which is just east of Greenwich Time (Universal Coordinated Time), so it is one hour later in the CET Zone than in London. By MT I presume you mean Mountain Time, not the state of Montana, most of which is in the Mountain Time Zone anyway, which is 2 zones west of Eastern Time. Eastern Time is 5 zones west of Greenwich, so MT is 8 time zones west of CET. So when it is 10 am CET it is 8 hours earlier in the MT zone, or 2 am. That is assuming both zones are on standard time and not Daylight Savings Time or Summer Time, etc.
South Africa is GMT + 2 CET is +1 So South Africa is one hour ahead of CET time.
