Differences Between Military and 24 Hour Time Garmin Customer Support

POSIX programs such as ls default to displaying timestamps in 24-hour format. The history of military time can be dated back to the Early Egyptians in the 11th Dynasty. The first appearance of a 24-hour clock was found on a coffin lid which is famously known as the Diagonal Star Table. The Egyptians synchronized the time system with certain patterns of constellations that passed through the sky at night. This system was defined by the different amounts of light intensity that was present during the day and season. The constellation patterns would eventually develop into a year with 360 days. Military time format uses 24 hour time format instead of 12h am, pm time format. Military time uses a 24-hour clock while civilian time uses a 12-hour clock. In general, in civilian life, the standard 12-hour clock is used in the United States and Canada, while the 24-hour clock is used in many other countries. The U. S., Canada, and other countries use the 24-hour clock for their military. Note that the colon between the hour and minutes is omitted in writing military time. All using military time will synch their clocks and watches to a master clock. The Department of Defense (DoD) uses one clock, also known as the atomic clock (mighty cool nickname), to ensure pinpoint accuracy and that all teams are using the exact same time. The Precise Time Department (PTD) part of the U.S Naval Observatory has maintained a Time Service Department since 1880.
