Please note that the world is not divided into 24 equal time zones. Each time zone has deviations around countries and parts of countries.
The map in WorldTimer depicts the 24 world time zones according to longtitude and does not attempt to display all of the intricate details of each time zone. The main reason for this is the size and scale of the map itself. The time zones on the map are intended as an indication only. If a large number of requests are received for an accurate representation of time zones, this feature may be added in the future.
