Another solution

: /t  ( ca u -- sec min hour )
    3        \ a count, decremented every recurse
    [: -rot dup 0>
       if 0. 2swap >number 1 /string 2swap drop ( -- ct ca' u' n1 )
          >r rot 1-
          recurse r> swap exit
       then 2drop
    ;] execute
    0 ?do 0 loop   \ 0 hours and minutes if missing in source string
;
: .t   cr . ." hr "  . ." min " . ." sec " ;

cr
s" 1:2:3"    /t .t
s" 02:03"    /t .t
s" 03"       /t .t
s" 23:59:59" /t .t
s" 0:00:03"  /t .t
s" " /t .t
s" :" /t .t
s" :53" /t .t
s" 11/12/13" /t .t   \ Different separator
s" 11::13" /t .t
s" :::" /t .t
s" 3:" /t .t
s" 1:2:" /t .t

The last two could be regarded as wrong but you indicated elsewhere that 
they wouldn't occur.

Any non-digit is a separator
