The history of military time starts in the Egyptian times, specifically the 11th Egyptian dynasty (est. 2100 B.C.). It was the Egyptians who first used the 24-hour clock, and proof was found on a coffin lid known as the Diagonal Star Table. Later on, as warfare progressed, various military forces had to improve their strategy and communications. Hence, military or 24-hour time was adopted to improve accuracy, as the slightest mistake in exchanging information could lead to the wrong move.
