title: Comparing two abap time/date stamps
body: <p>I have two variables:</p>
  
  <pre><code>data: 
  var_a like sy-timlo,
  var_b like sy-timlo.
  
  var_a = sy-timlo.
  
  " do other things here    
  
  var_b = sy-timlo.
  </code></pre>
  
  <p>In case I have a whole bunch of those time-variables, can anyone tell me how I can order them ascending/descending?</p>
