或者
function Format2(sec) {
const oneHour = 3600;
const oneMin = 60;
let hour = (sec / oneHour) | 0;
console.log(hour.toString().padStart(2, "0"));
let min = ((sec % oneHour) / oneMin) | 0;
console.log(min.toString().padStart(2, "0"));
let sece = (sec % oneHour) % oneMin | 0;
console.log(sece.toString().padStart(2, "0"));
}
Format2(sec);
