View the difference between local time and GMT/UTC

GMT is both a time zone and the reference point for the Prime Meridian

Everyone's local time is just a glance away, whether it is on a digital device or displayed by traditional timepiece, a clock or a watch.

Not everyone lives in the same time zone though, so local times differ.

The difference between time observed in a certain time zone and GMT is also called offset.

Find out what why the Prime Meridian is so important for the time zone structure.
