Bug fix:

variable cnt

: @SEC ( a u -- ud )  \ HH:MM:SS or free-form
  0 cnt !  3 0 do
    0 0 2swap >number rot drop ( u ... a u)
    dup if  1 /string  1 cnt +!  then
  loop 2drop  cnt @ 1+ 0 do  rot  loop ( fixup)
; \  swap secs/min * +  swap secs/hour um*  rot 0 d+ ;

: .3 ( h m s -- )  cr rot . swap . . ;

s" 00:00:06" @sec .3
s" 00:06:00" @sec .3
s" 06:00:00" @sec .3
cr
s" 06"       @sec .3
s" 06:00"    @sec .3
s" 06:00:00" @sec .3
