*** Quoting Michael Haritonov from a message to All ***

MH> So, 12AM is ... ? 12 AM or 12 PM? I mean - it's a zero _before_ 
MH> midnight or _after_ midnight?

2259 is 11:59 PM
0000 is 12:00 AM (midnight)
0001 is 12:01 AM

It's the same way in the military and amatuer (ham) radio.  We use
UTC/Zulu/GMT ¨though and not our own time zone.

Hope this helps.

Later,
Sean
