Greenwhich Mean Time (GMT) was established to aid worldwide oceanic navigation and is based on the rotation of the Earth. It was not until the British railway system started using GMT in the mid 1800s that GMT was adopted “for land use”. And it was not until the late 1800s that GMT was adopted universally. At this time, the 24 time zones were created along with the International Date Line. During Daylight Savings Time, GMT is 4 hours ahead of Eastern Daylight Time (EDT)
