Tests:

  • If and modulo array

     
    var y = [];
    if (z>3600){
        y.push(Math.floor(z/3600));
    }
    z%=3600;
    if (z>60){
        y.push(Math.floor(z/60));
    }
    z%=60;
    if (z>0){
        y.push(Math.floor(z));
    }
    t = y.join(":").replace(/\b(\d)\b/g,"0$1");

  • Ternary and slice concatenation

     
    t = ("0"+Math.floor(z/3600).toString()).slice(-2)+":"+("0"+Math.floor(z%3600/60).toString()).slice(-2)+":"+("0"+Math.floor(z%3600%60).toString()).slice(-2)
