Why do you think some countries follow one time zone only?
Some of the countries are so big, i.e. they cover a land area, so large, that more than one set of 15 degrees of longitudes intersect the country, thus resulting in two or three or more time zones in that country. This is why some countries have more than one time zones.
Are time zones geographical?
Standard time zones can be defined by geometrically subdividing the Earth’s spheroid into 24 lunes (wedge-shaped sections), bordered by meridians each 15° of longitude apart. The local time in neighbouring zones is then exactly one hour different.
Why do some countries have many time zones in geography?
As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. As your location on Earth rotates into sunlight, you see the sun rise. Since different parts of Earth enter and exit daylight at different times, we need different time zones.

Which countries have different time zones in the world?

Why is time set earlier in the west than in the east?
Each line is one hour earlier than the last line to the east, but within the boundaries of the time zone itself, time is not set earlier in the west than in the east. Many countries in South America deflect time zone lines around their boundaries so that the entire nation is within the same time zone.
Why are time zone lines not always straight?
