• B. to get to work on time
• C. to make clock time the same for large parts of Earth
• D. None of these

Answer 1

Answer: (C)

to make clock time the same for large parts of Earth

Stanford Fleming was first to propose a standard time which has a single 24-hour clock for the entire world, located at the centre of the Earth, not linked to any surface meridian.

It is important to have time zones because we can have a standard time that is same for larger parts of the earth.

Since different parts of Earth enter and exit daylight at different times, we need different time zones.
