About the London-Reykjavik gap
London sits in the Europe/London time zone (BST), while Reykjavik uses Atlantic/Reykjavik (UTC). That puts Reykjavik 1 hour behind 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 10:00 to 17:00 in London. Booking inside that band means neither party is dialling in before breakfast or after dinner.
