here's what i'd like


   inclusive_endpoint = Time.now + 7.days

   runt.next_times inclusive_endpoint  #=> array of all times covered between
                                       #   now and endpoint, 'now' should be an
                                       #   optional parameter so multiple calls
                                       #   can be made transactional, eg
                                       #
                                       #   runt.next_times inclusive_endpoint, 'now' => Time.now
                                       #   runt.next_times inclusive_endpoint, :now => Time.now
                                       #

that way it's easy to do

   loop{
     now = Time.now

     inclusive_endpoint = now + sleep_interval

     runts.each do |runt|
       times = runt.next_times inclusive_endpoint, :now => now
       schedule_all_events times
     end

     sleep_until inclusive_endpoint
   }


make sense?

thanks for a great lib btw!
