Did you know?

1884 was the year when an international conference agreed to divide the world into time zones, each one representing about 15 degrees of longitude or the equivalent of an hour. That made it in all 24 integer time zones. Currently, there are more than one-hour time zones and several half-hour ones.
As the Earth rotates on its axis once every 24 hours, each degree of longitude will show a 4-minute difference in solar or local time, as displayed by a sundial.
China, despite covering 62 degrees of longitude, has chosen to use just one time zone.
