Calcultaing time

[Jan Erik Moström]

Before trying to find some time to do this myself I would like 
to check if someone has an Applescript that would calculate time 
of iCal entries in OO. I imagine something like this

2006
     Calendar 1          3:13
         Jan             2:03
             entry 1     0:33
             entry 2     1:30
         Feb             1:10
             entry 3     0:40
             entry 4     0:30
         ...
     Calendar 2          1:23
         ...

etc

Or like this

2006
     Jan
         Calendar 1
             entry 1     0:33
             entry 2     1:30

You get the idea.
