I am working on developing a system that calculates the time worked on my company's projects. For each project I have a SpanSet representing the time reportedly worked on each project and need to eliminate all time for weekends and work holidays.
My approach has been to build a spanset for the weekends and holidays and use the 'complement' function to remove that time from the project. $slatime = $project_spanset->complement( $weekends_and_holidays_spanset ); This works fine, but it is terribly slow on my system. It takes over one seconds per project to compute, and we have over 10,000 projects. Is there a way to speed it up given that we are ONLY working with full days? (i.e. the weekends and holidays we are trying to subtract are complete days) Thanks!!! Rick Ferrante
