It is better to represent it with 0000.
both 0000 to 1200 is AM, and 1200 to 0000 is PM.
In the military version, the 24-hour day is counted from 0000 to 2359. Midnight is represented as 0000 hours, and the hours are counted sequentially from 01 to 23, with noon being 1200 hours. For example, 3 PM is written as 1500 hours, and 11 PM is 2300 hours. This system eliminates ambiguity between AM and PM times.
1200 PM refers to noon in a 12-hour clock format, indicating the time at 12:00 in the afternoon. It marks the transition from morning to afternoon. In a 24-hour clock format, this time is represented as 12:00.
Use the 24-hour clock to prevent mis-understanding, as Europe and the US Military: 1200 is Noon, 0000 or 2400 is midnight. Thanks - I agree but that doesn't solve the computer time clock problem. The slot to the right of 12:00 on my system always has either AM or PM. Most of North America uses a 12 hour clock so the problem is not solved by switching to a 24 hour clock. Greenwich doesn't have an answer - "12:00 AM and 12:00 PM have no meaning." http://wwp.greenwichmeantime.com/info/noon.htm

No 1200 hours is midday. Midnight is 0000 hours (zero hundred hours)
1200 hrs. There is no such corresponding time for midnight. Reason midnight could be either '0000' or '2400'. , but which day does it refer. So midnight on the 24 hour clock does not occur. You have either 2359 hrs (on a given day) or 0001 hrs. ( the next day), that is 2 minutes later. .
both 0000 to 1200 is AM, and 1200 to 0000 is PM.
It's a 24 hour clock, so no AM or PM. The first two digits are hours, second two are minutes. The day starts at midnight, which is 2400 of yesterday and 0000 of today. Everything after noon (or 12:59 PM to be precise), you just add 1200 to the time. From midnight to 1 AM the hour is 00 (i.e. you subtract 1200 from civilian time.)
12am in military time is 0000 or 00:00 ("zero hundred" or simply "midnight") 12pm is 1200 (twelve-hundred. Or midday)
AM (Ante Meridiem, Latin for Before Midday) is between 0000 and 1200, and PM (Post Meridiem, Latin for After Midday) is between 1200 and 0000.
Usually, 2400 hours (some say 0000 hours).
Noon is 1200 hours. Midnight is 2400 hours. I've also seen 0000 hours for midnight.
Are we talking of 12 noon or 12 midnight. 'pm' means 'post meridian' (Latin) for 'afternoon'. If it is 12 noon it is neither before nor after noon , it is 12 NOON. A similarl argument holds for 12 midnight. 'am' are the Latin initials for 'ante meridian ' ; before noon'. In military time ; 12 noon is 1200 hrs. 12 midnight is NEVER used because of confusion over the date/day . The time of '0000' and '2400' is the same instant. So to avoid confusion the earliest/latest times used are 0001/2359 hrs respectively.
