Ok I took the time differences between each time zone from that picture of Biden at “Camp David” added each together that I posted last bread.

Washington is 5 hours behind of London.

***London is 2 hours behind of Moscow.

***Moscow is 1:30 hours behind of Tehran.

Tehran is 3:30 hours behind of Beijing.

Beijing is 1 hour behind of Seoul.

In this picture London is behind Moscow 3 hours and Moscow is 30 minutes behind Tehran
