Understanding GMT and 24-Hour Time
The 24-hour time format, also known as military time, splits the day into 24 hours. Hours run from 0 to 23, unlike the usual 12-hour AM/PM system. In this system, 12:00 PM is shown as 12:00 hours, 1:00 PM is 13:00 hours, and so on, up to 24:00 hours, which is midnight.
Time Zones and Greenwich Mean Time
This 24-hour format goes hand in hand with GMT, the global time standard based on Greenwich, England’s time zone. GMT is the base for time zones worldwide, with each zone’s time related to GMT. For instance, the Central Time Zone in the U.S. is 5 hours behind GMT. So, 10:10 AM in the Central Time Zone is 15:10 GMT.
The first clock to show Greenwich Mean Time to the public was the Shepherd gate clock in 1852. Greenwich Mean Time became Britain’s official time in winter. It’s still used by groups like the Met Office, Royal Navy, and BBC World Service.
“Rolex GMT-Master and GMT-Master II models have made the GMT feature popular. They have a 24-hour hand and a rotating 24-hour bezel.”
GMT watches let users set a second time zone, with the main hand for local time and the 24-hour hand for another zone. The bezel can also track a third zone.
