a method of designating time by using the numeric sequence from 00 to 23 for the hours and the numbers 00 to 59 for the minutes in a daily cycle beginning with 0000 (midnight) and ending with 2359 (1 minute before the next midnight). The system provides a clear distinction between prenoon and afternoon time without requiring the designations AM and PM. Also called military time.
