What time is it around the world? From the time on the clocks can you work out how many hours ahead or behind Universal Time each of the cities is? Does this agree with their time zone on the map?
The UK is in time zone zero. The time zone to the east of Greenwich is one hour ahead of Universal Time (UT+01:00) while the time zone to the west is one hour behind (UT -01:00) and so on for all the other time zones.
