* In the so-called French system now in use by the armed forces of 
the United States, each day begins at midnight, and time is counted 
in four figures, without the use of a.m. and p.m. Thus 1:00 a.m. is 
0100, 8:35 a.m. is 0835, noon is 1200, 5:40 p.m. is 1740 and so on 
up to 2400, which is midnight.
