You are probably right. The fact is that:
1) when you clock in and out, you can get negative durations (I
know, it seems weird...) and then your clock table is wrong
(negative duration are not taken into account when
calculating the sums). Anyway, I think it should be good to
support negative durations in order, for example, to compute
differences between durations (which can lead to positive or
negative times);
2) I'm still unable to sum positive times value in my table (see
my problem 2) in my previous email). Is there a specific
operator in order to sum times?
Thanks,
F.
