About the London-Johannesburg gap
London sits in the Europe/London time zone (BST), while Johannesburg uses Africa/Johannesburg (UTC+2). That puts Johannesburg 1 hour ahead of London right now.
These two cities do not handle daylight saving the same way, one adjusts its clocks seasonally and the other does not. The difference between them therefore moves by an hour twice a year, which is a common cause of missed meetings. The clocks above always show the live position rather than an assumed offset.
For scheduling, the practical overlap runs from 09:00 to 16:00 in London. Booking inside that band means neither party is dialling in before breakfast or after dinner.
