How much time do I spend in meetings?

[Daniel J. Sinder]

I spend an unfortunately large portion of my time at work in meetings. 
I keep track of my meetings in a file 'meetings.org' where, for each 
meeting, I may also keep notes.  For example, the structure looks like this:

* 2009
*** <2009-06-08 Mon 16:00-17:30> Meeting 1
*** <2009-06-08 Mon 15:30-16:00> Meeting 2
*** <2009-06-08 Mon 15:00-15:30> Meeting 3
***** If I have notes, they're under the heading
       - More information
       - about this meeting
*** <2009-06-08 Mon 14:00-14:30> Meeting 4
*** <2009-06-08 Mon 11:00-12:30> Meeting 5
*** <2009-06-08 Mon 10:00-11:00> Meeting 6
*** <2009-06-05 Fri 15:30-17:30> Meeting 7
*** <2009-06-05 Fri 13:30-15:30> Meeting 8
*** <2009-06-05 Fri 11:00-13:30> Meeting 9
*** <2009-06-05 Fri 10:00-10:30> Meeting 10

For many meetings, I don't take notes....or don't even take my laptop to 
the meeting.  However, I'd still like to summarize/report the time I 
spend in meetings, but clocking in/out seems entirely redundant.  After 
all, the time I spend in the meeting is already in the headline's time 
stamp.

For now, I go through each meeting headline at the end of the day, 
clocking in/out, and adjusting the times to match the time stamp.  It's 
a silly exercise in redundancy.

Is there a better way to do this?  For example, is there some way to use 
the meeting time stamps directly in clock summaries/reports (as if I had 
clocked in/out at those times)?

I'm not looking for a new feature here, just curious if there's a better 
way.

Thanks,
Dan
