How do you calculate world time zones?
- The station A is at 60° West with local time 6:30 PM.
- Station B has local time 4:30 PM.
- Now,we can find that the time difference between the two stations is two hours.
- Since 15° is covered in one hour, in the same way 2 hours would cover 30°.
- Simply add 30 degrees to station A location i.e 60°.The answer would be 90°.

Personal communications, airplane and shipping schedules, international meetings, transport – the entire system would collapse if there was no timekeeping system to ensure we’re all on the same page. Or time, as it were.

In some countries where English is spoken, the term Greenwich Mean Time (GMT) is often used as a synonym for UTC.
