libdatetime-event-recurrence-perl 0.18-1 (powerpc binary) in ubuntu xenial

 DateTime::Event::Recurrence provides a way to create sets of DateTime objects
 that recur at specified intervals. Often, you will want DateTime::Set objects
 for dates that should occur at intervals like "once a month" or "every day."
 .
 More complex relationships can be created too, such as, "every Monday,
 Wednesday and Thursday at 10:00 AM and 2:00 PM."
