Late reply but yes, those sort of date range options do seem to be relative and not fixed on the day the report was created. I've not used the 'Current term' option myself but have used 'Today', which dynamically changes the date range to the day you are on; a bit like =TODAY in Excel. So, if I created an attendance report on the 1st May with 'Today' and viewed that same report on 16 May, the data is reflective of 16 May, not 1 May.
