   You did not provide output for test cases.   
      
   I expect that "03" is equivalent to "03:00:00", which means 3 hours, 0   
   minutes, 0 seconds.   
   And ":03" is equivalent to "00:03:00", which means 0 hours, 3 minutes, 0   
   seconds.   
      
   My above implementation for `/t` produces:   
      
      s" 1:2:3"   /t .t   \ "1 hr 2 min 3 sec"   
      s" 02:03"   /t .t   \ "2 hr 3 min 0 sec"   
      s" 03"      /t .t   \ "3 hr 0 min 0 sec"   
      s" :03"     /t .t   \ "0 hr 3 min 0 sec"   
      
      
   What is wrong?   
      
   Maybe your `>int` works incorrectly with an empty string?   
      
      
   For testing I use:   
      
      : >int ( sd.number -- u ) 0. 2swap >number 2drop drop ;   
      \ the empty string produces 0
