mark krdo j please
As the local TIMe differs by 4 minutes at every longitude, it would create a lot of confusion regarding time for any country as a whole which may stretch across several longitudes. Therefore each country selects a central meridian and the local time of this meridian is the standard time of that country.
Time zone. ... A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.
More Than 24 Time Zones. If each time zone were 1 hour apart, there would be 24 in the world. However, the International Date Line (IDL) creates 3 more. Also, several time zones are only 30 or 45 minutes apart, increasing the total number of standard time zones even further.
