You can use this li'l function to convert your secs to SMPTE (Lite :-)

function smpte_lite dauer1
   set the numberformat to xx
   put dauer1 div 60 into minu
   put dauer1 mod 60 into seku
   return "00" & ":" & minu & ":" & seku
end smpte_lite

Use it this way:

...
    put smpte_lite(the secs - the_startsecs) into fld "timer"
...

Hope that helps
