title: Propel - checking date
body: <p>Are function of Propel to checking date? For example i have in database:</p>
  
  <p>2011-12-28 11:11</p>
  
  <p>i would like get this if current date is higher of 1 days.
  if current date == 2011-12-27 11:10 then should be return OK, and if current date == 2011-12-27 11:12 should'nt return OK.</p>
