I tried to set a timestamp "thu 12:00+1.5", using C-c . and typing the
characters in quotes. What I got was
<2010-08-12 Thu 12:00-13:00>
I found that 12:00+1:30 works fine, but it seems like 1.5 should be
parsed.
Separately, I'd like 24-hour time without colons to work. "thu 1400"
seems unambiguous, but just shows up as thursday without a time.
I don't know how hard these are or if there are reasons not to, but I
thought I'd throw out the idea.

It is certainly harder to make Org's parsing capacity even more elastic
than to let our brains parse this directly :)
12:00+1.5 looks weird to me and computing 1.5->1:30 is straightforward.
Same for 1400->14:00.
But maybe other people think otherwise...

I think Greg's point is about entering data using only numeric keypad. I
can confirm that I have considered these issues (esp. 1400
vs. 14:00). Fractional hours don't seem to be that easy as there are
countries like Poland where you use comma as decimal point (working with
Emacs' built in calc is a pain) which earns another few lines for
parsing code.

AFAIC, I won't mess with this part of the code, I think it's quite easy
enough to enter 14:00 instead of 1400... patch welcome ;)

Not really in fact if you use keypad. It's not about the number of
keystrokes but their layout. Try it.

ASAP ;)

Hi Lukasz,
the problem with making the parser more general is that it might
start to interpret years as durations and the other way round.
You are welcome to submit a patch - but it would have to be a careful
one.

I'm curious if using the decimal point on the numeric keyboard instead
of the ":" colon would be the simplest solution in time durations too
... e.g 14:00+1,30. (add one hour 30 minutes). But knowing how clever the
parser is that might step on the shoes of other hidden cleverness I am
unaware of.
