Note that military time doesn’t use a separator between the hours and the minutes. At 12 am (midnight), the hour count is reset to 00. In other words, for the period from 1 pm to 12 am, you have to subtract 12 to convert to the 12-hour format. The real fun starts after 12 noon when the 12-hour system jumps all the way back to 1 while the 24-hour system just keeps counting upward. The 24-hour clock is the world’s most widely used time format, while military time is only used in some contexts, such as the military and emergency services. It uses a special notation and pronunciation geared toward clarity and conciseness.Īlthough it is often used as a synonym for the 24-hour clock, and the two are closely related, they are not the same.

If you ever have some free reading time, check up on the standards of measurement on a global basis. If we knew the calculations, astronomical observations, worldwide coordination, and the international time associated groups that keep our clocks running on time, it would be more than the average person could handle! UTC was internationally implemented replacing GMT.

The International Time Bureau coordinated an international/universal coordination of time/frequency which became known as UTC.

Naval Observatory all agreed to coordinate time/frequency transmissions based on UT2.

The Royal Observatory (Greenwich,) National Physical Laboratory England, and the U.S.

UT2 – did the same thing UT1 did but used a seasonal variant to account for the Earth’s rotational speed seasonal difference. UT1 – did the same thing UT0 did but also measured the position of the pole in respect to the site that was observing it making small corrections to be able to produce a time scale. UT0 – measured the Earth’s rotational axis in respect to a site that was observing it.

The International Astronomical Union (astronomers) recognized that there were three versions of their “universal time.”.

This changed did not apply to the general population as it was adopted for astronomical research only.“Universal time” replaced the astronomoer’s GMAT.The International Astronomical Union (astronomers) replaced GMT with what was referred to as “universal time” although it was not yet recognized as UTC.This new time was called Greenwich Mean Astronomical Time (GMAT.) GMAT was the standard by which astronomers measured time. Astronomers introduced a 12-hour break in the continuity of time causing a loss of 12 hours.Astronomers continued to research time measuring it daily, noon to noon.Through a timeline, we can see how history changed the way time is measured and was coordinated worldwide. Greenwich Mean Time (GMT) was adopted thereafter and recognized around the world. In 1884, the International Meridian Conference held in Washington DC decided that the Prime Meridian in Greenwich, England would serve as the point of which all time zones in world would be measured from. Greenwich Mean Time (GMT) was officially replaced with Universal Coordinated Time (UTC) in 1972 as the universal standard of time.Īstronomers over the past hundreds of years have perfected the way to tell time!Īn example of UTC as you would see it on time.is/UTC The History Behind UTC This measurement of time is used to centrally regulate and set our clocks to. Universal Coordinated Time (UTC) is the standard 24-hour measurement of time used worldwide.
