i placed the text already, but it does NOT look right where it is, please fix... there are two places where this information might be relevant, but i put it in the part that references the joint Communication protocol as the usages appear to contradict each other PerkinsC (talk) 20:36, 7 April 2014 (UTC)
the Correspondance Manual covers everything from eMail traffic to hard Copy letters that are sent through the mail. the Exact Text Follows

15. ExpressingMilitary Time. Express military time in four digits based on the 24-hour clock.

The time range is 0001 to 2400. The first two digits are the hour after midnight and the last two digits are the minutes. Do not use a colon to separate the hour from the minutes. EXAMPLE: 6:30 am in civilian time is 0630 in military time

3:45 pm in civilian time is 1545 in military time"

Can the "hundred" be dropped?[edit]

Can the "hundred" be dropped when saying the time in 24-hr notation? For example, is it okay to say "thirteen" instead of "thirteen hundred"? Thanks. (talk) 16:24, 9 July 2017 (UTC)

@ I live in the UK (and have lived in other English-speaking countries) and we use 24-hour notation regularly. But never verbally or written out in words (only numbers, i.e. 21:15 is spoken as "nine fifteen PM" or "quarter past nine"). What you are talking about is military time (distinct from normal 24-hour notation), and there are regulations on how to use it verbally. I've only seen it being used in films and fiction books. I hope that helps you as you search for your answer. This might help: --BurritoBazooka Talk Contribs 17:46, 9 July 2017 (UTC)
the "hundred" is to indicate that it is 00 minutes... PerkinsC (talk) 19:32, 5 September 2017 (UTC)

Leading zeros?[edit]

Do you have to include leading zeros in the 24-hour clock? I am not talking about military time, i am talking about the regular 24-hour clock. I hate leading zeros and can they be dropped? For example, is it okay to say 9:00 instead of 09:00? Thanks! (talk) 14:55, 30 July 2017 (UTC)
