The default RRA stores primary data points for a day. More RRA can be added for a week, a month, a quarter and a year. The created RRD is for an acquisition period much less than a day, typically about some minutes or a few hours.
This constructor neads an argument named step which is the period of acquisition. The natural step units are the minute(mn) and hour(h), although second(s) is allowed.

$creator = RRDTool::Creator::DayPDP(-step => "10mn") ; $creator->add_RRA(-duration => "week") ; $creator->add_RRA(-duration => "month") ; $creator->add_RRA(-duration => "quarter") ; $creator->add_RRA(-duration => "year") ;
