Thanks a lot to those who responded to my time formats question.
Here are the answers I received:
----
I'm quoting from "American Usage and Style: The Consensus" by Roy H.
Copperud, 1980.
"Whether a.m. and p.m. are capitalized is an arbitrary matter that
publications settle in their stylebooks. The lower case seems predominant.
----
According to the Chicago Style of Manual: 8 A.M. (in small caps)
According to the Gov't Printing Office Style Manual: 8 a.m.
----
According to Microsoft's Manual of Style for Technical Publications, the
correct form is 8 A.M.
----
If you're figuring continental US, it's 8 A.M. or 8 a.m., because a.m. and
p.m. are abbreviations for two words (ante meridien and post meridien,
respectively).
