  'seven_day':  Statistics for the last seven days, i.e., since midnight
                seven days ago.  For example, "what is the maximum wind
                speed in the last seven days?"
                $seven_day.wind.max

  'thirty_day': Statistics for the last thirty days, i.e., since midnight
                thirty days ago.  For example, "what is the maximum wind
                speed in the last thirty days?"
                $thirty_day.wind.max
                
  'last_month': Statistics for last calendar month, this is useful in
                getting statistics such as the maximum/minimum records.
                $last_month.outTemp.max at $last_month.outTemp.maxtime
                $last_month.outTemp.min at $last_month.outTemp.mintime
    
  'last_year':  Statistics for last calendar year, this is useful for
                things like total rainfall for last year.
                $last_year.rain.sum
  
  'last_year_todate': Statistics of last calendar year until this time
                      last year. This is useful for comprisons of rain
                      fall up to this time last year.
                      $last_year_todate.rain.sum
