Use "start=${StartTime}" and set StartTime in the script you use to call RRD.

RRD does not have any concept of "week", "month", "year" - and only limited concept of "day" given that "midnight" is only "midnight in UTC timezone". That means you need to do some work external to RRD if you need to work with calendar periods.
