How do you get negative times by clocking in and out?  The only way I
can think of that you can get negative time is if you edit the clocked
values after they are created.  By definition you have to clock in
_before_ you clock out (right?) so everything clocked should be 0
minutes or positive.  Am I missing something?

I'm not sure what the answer to this is.  I use the clocking features to
summarize time spent working on tasks in clock reports only and I've
never had the need to deal with negative values or summing clocked
values manually in a table.

Maybe other users have experience with summing times in tables outside
of clock reports?
