Hi,

Schreibt man korrektwerweise am - groß/klein/mit/ohne Punkt/Leerzeichen?

http://en.wikipedia.org/wiki/Ante_Meridiem#Abbreviations:
“The Latin abbreviations a.m. and p.m. (often written "am" and "pm", "AM" and "PM", or "A.M." and "P.M.") are used in English, Portuguese (Brazilian), and Spanish.”

http://en.wikipedia.org/wiki/12-hour_clock#Typography:
“It is technically correct to write "a.m." and "p.m." as the periods (full stops) denote that the words "ante," "post," and "meridiem" are abbreviated. Depending on the style guide referenced, the abbreviations "AM" and "PM" are variously written in small capitals ("am" and "pm"), uppercase letters ("AM" and "PM"), or lowercase letters ("am" and "pm").
There are symbols for "a.m." (U+33C2 = "㏂") and "p.m." (U+33D8 = "㏘") in Unicode. They are meant to be used only with CJK fonts, however, as they take up exactly the same space as one Chinese character.
Some stylebooks suggest the use of a space between the number and the a.m. or p.m. abbreviation.”
