// current seconds
let seconds = date_ob.getSeconds();

// prints date in YYYY-MM-DD format
console.log(year + "-" + month + "-" + date);

// prints date & time in YYYY-MM-DD HH:MM:SS format
console.log(year + "-" + month + "-" + date + " " + hours + ":" + minutes + ":" + seconds);

// prints time in HH:MM format
console.log(hours + ":" + minutes);
