Up until now the time & attendance or missing time report grouped daily data by week. Now you can group by month or by payroll period as well as week, by selecting the group-by menu at the top. If you group by an option other than week the daily totals for timesheet vs. attendance vs. absence vs. work-schedule hours are still shown, but the group totals are now calculated on the basis of a month or payroll period. Payroll periods can be defined under System > Set up HR > Periods
