Hi, ok, im trying to find the best and most effecient way to do the following:

* we have an employee availability for a particular day i.e Monday defined by 2 times (java.sql.Time) i.e start time and end time.
* we have 'unavailability intervals' for advisors throughout the day defined using startDate endDate (java.util.Date)
I
Problem: I want to calculate the number of hours they are 'available' i.e the general availability times minus the unavailability times.
Is there some cunning set union/intersection based theory that i could apply or is it just a case of hammering out some standard calendar methods and/or getting time as a 'long' then doing some form of millisec substractions etc.....thoughts anyone?

yeah, i'd looked at joda time but it didn't seem to provide this kind of functionality and seemed to be more of an api to tighten up the standard java date/time api?

This is the best timing api (it is planned for inclusion for Java 7), so this is the best starting point you can have.
