What is the correct way to type am or pm, when it comes to time? If
it's four in the morning, is it:

A. 4am
B. 4 a m
C. 4AM
D. 4 a.m.
E. A.M

And so on... is there a correct way on how am or pm should be typed
out?

For me, it has to be in your form "D": a.m.

That said, I prefer to use the 24-hour clock whenever I can.

For me too. But lots of people prefer 4 A.M. (which is what I suppose E
is supposed to be). I've never seen B, but all the others have some
currency.

There are lots of ways. You just selected a few of the incorrect
ones.

Use:
4 AM
or
0400

Is this your own idea of correctness, or do you know of a style guide that
recommends capitalising it?

The only reference I can put my hands on quickly (Burchfield) definitely
recommends "a.m.", with "am" as an alternative.

CMoS no longer prefers it but still permits it in small caps, and
prefers to omit the periods (calling them "unnecessary" but not wrong)
when it's in caps.

I would say 'am' too - the use of full stops after initals or abbreviations
is rarely used here these days.

I wrote a few articles for a technical magazine, and there were
mandatory editorial 'guidelines' for grammatical* abbreviations, etc.

The policy was that they should be, far as possible, lower case, without
any avoidable full stops, periods or other punctuation clutter.

The allowable (and logical) exceptions were if an abbreviation, where
used, could (or would) be ambiguous or misinterpreted. So, an initial
"Television" would be "TV" (not "Tv"), but, thereafter in the sentence,
it would be "tv". However, "intermediate frequency" would be (initially)
"I.F.", otherwise i.f.
* Standardized abbreviations for things like physical and engineering
units were not included in this policy.

This seems to be the current standard. My "A Handbook for Writers of
English" by John G. Taylor says:

"Previously, capitals were encountered: A.M. and P.M. these are always used

the year of the world; PM = Prime Minister.)"

Intermediate Frequency is not a unit, but it's still an engineering
term that I've always seen as IF. Surely you wouldn't write v.h.f.
for Very High Frequency, would you?

Use d: 4 a.m.

In full typography, intended for formal printing in a book or
magazine, some publishers still like small caps.

This is a style thing and you'll find different answers.
The
style I follow is 4 p.m.
I leave the space, and I put in the
periods.
You'll see many variations.
Just make sure you don't
write 4PM in one paragraph and 5:30 p.m. in the next.

Of course not. The guidelines requested that it be written as "i.f." (so
that it could not be misread - even momentarily - as the normal word
"if"), and not "IF" or (unless it starting a sentence) as "I.F.". "For
example" and "that is" would be respectively "eg" and "ie", and not
"e.g." or "E.G.", or "i.e." or "I.E."

I'm pretty sure that LF, MF, HF, VHF etc were indeed lf, mf, hf and vhf.
Although they are lower-case, you can't mistake them for any normal
words. [These days, I follow the normal convention, and use upper case
letters.] Units like milliamps and decibels were still the standard mA
and dB.

Thanks. How did I do that. Does this mean I have to repeat the first

I deal with a lot of date information in computer readable form, and
the most "normal" form that I see 99% of dates in is AM or PM. I'm not
sure that's applicable to something formal, like a book or an article.

The problem I have with using the periods, is that I get stuck on
whether to put a space after the first one.

I can only repeat that I've never seen those frequency bands printed
any way but capitalized without periods, and leave it at that.
Obviously YMV.

Having worked extensively with UHF, VHF, and MW in both a military and a
civilian capacity, and having been a long-time SW DX-er in the LW, MW and SW
bands, I agree. Next thing you know, Q-signals and Z-signals will be written
with small letters. Sinpo code? Int qrk?
