startOffset property
startOffset specifies the start date of the extended reporting date
range for a cohort report.
startOffset is commonly set to 0 so that reports contain data from the
acquisition of the cohort forward. If granularity is DAILY, the
startDate of the extended reporting date range is startDate of the
cohort plus startOffset days. If granularity is WEEKLY, the
startDate of the extended reporting date range is startDate of the
cohort plus startOffset * 7 days. If granularity is MONTHLY, the
startDate of the extended reporting date range is startDate of the
cohort plus startOffset * 30 days.
