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


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.

 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...
