How do I convert seconds to hh:mm:ss in Javascript ?

I can use a construct event like this

Set Text to zeropad(floor(t/3600),2)&":"&zeropad(floor(t/60%60),2)&":"&zeropad(floor(t%60),2)

..but how would I do this in a JS snippet? (as zeropad is a construct 3 command).

I guess the question is really how do I access C3 expressions from script.

Thanks

I guess the question is really how do I access C3 expressions from script.

That I don't know, but that should work in JS Script with c as a global Variable;

let t= 10*3600+15*60+20; 
let s,m,h;

h= String(Number(Math.floor(t/3600)));
m= String(Number(Math.floor(t/60%60)));
s= String(Number(Math.floor((t%60))));

runtime.globalVars.c= h.padStart(h.lenght-2,'0')+":"+m.padStart(m.lenght-2,'0')+":"+s.padStart(s.length-2,'0');
