Military Time

Military time is used to more accurately and easily track the passing of each hour throughout the day. A 24 Hour Clock written as 00:00 where the first two digits are the hour between 00 (midnight) and 23 and the second two digits are the minutes from 00 to 59. It increments by hours from 00 to 23 and by minutes from 00 to 59; 11:59 PM being 23:59. The military clock is only local to its time zone base with UTC (Coordinated Universal Time) being most often used as it is easily adjusted to local time globally. UTC Military Time is called "Zulu Time" by the world's militaries, aviation industry and marine industry. Military time conversion is simple, for example military time 1600 is 4pm.
