Well I got to the point of doing extract (hour)*3600+extract(minute)*60+extract
(seconds) but then I have to recalculate this to a decent display. The user
will enter the data in the HH:MM:SS format so using intervals (which would
let postgres make easy calculations) would lead me to enter intervals 00:00:00-
HH:MM:SS or something like that. Maybe that's a better solutions. The question
is: Is time meant as Wall clock time because then it would make no sense that
it could be summed up.
