Attached is a patch to the code underlying 'i d' entries in the *Org
Agenda* buffer.  If a time of day is specified in the entry, it is
extracted from the entry and put into the timestamp of the diary entry.
(The .ics exporting code recognises these timestamps and therefore the
ics export code does not need altering.)

For example, given the following three entries added using 'i d' from
*Org Agenda*:

i d RET test 1 12:00-14:00 classes RET
i d RET test 2 did you get 7am wake up call? RET
i d RET test 3 find 3--5 volunteers RET

then the following entries are added to agenda.org:

*** 2010-02-03 Wednesday

**** test 3 find 3--5 volunteers
     <2010-02-03 Wed>
**** test 2 did you get wake up call?
     <2010-02-03 Wed 07:00>
**** test 1 classes
     <2010-02-03 Wed 12:00-14:00>

As this behvaiour may not be desired by all, I've currently put the code
conditional on org-agenda-search-headline-for-time being non-nil (the
default is t).  If that variable is nil, then the above three test
entries generates the regular tree:

*** 2010-02-03 Wednesday

**** test 3 find 3--5 volunteers
     <2010-02-03 Wed>
**** test 2 did you get 7am wake up call?
     <2010-02-03 Wed>
**** test 1 12:00-14:00 classes
     <2010-02-03 Wed>


Perhaps org-agenda-search-headline-for-time is not the right variable
though (happy to had another) given that it defaults to t?
