Diego, your best bet is to convert the date into a time. You'll need to 
extract the month, day, and year, then pass that into os.time().

function date2time(s)
   local m, d, y = s:match("(%d+)/(%d+)/(%d+)")
   if not y then
      return nil, "improper date format"
   end
   return os.time({ year = y, month = m, day = d })
end

t = assert(date2time("05/21/2009"))

Then you may compare these values.
