I have to convert seconds to time format:
seconds_1 = 540;
seconds_2 = -2820;
convert_1 = new Date(seconds_1 * 1000).toISOString().substr(11, 8);
convert_2 = new Date(seconds_2 * 1000).toISOString().substr(11, 8);
console.log(convert_1);
console.log(convert_2);it will return,
convert_1 : 00:09:00
convert_2 : 23:13:00
first one (convert_1) is correct, but the second one should return -00:47:00 .
The Actual issue is, the negative value is not converting to time correctly.
Please help.
I tried this,
function toTime(duration) {
// Hours, minutes and seconds
var hrs = ~~(duration / 3600);
var mins = ~~((duration % 3600) / 60);
var secs = ~~duration % 60;
let ret = hrs+ ":" + mins + ":" + secs;
return ret;
}
seconds_1 = 540;
seconds_2 = -2820;
console.log(toTime(seconds_2 ));A pragmatic solution is to remove the sign and then add it again:
function toTime(seconds) {
if (seconds < 0) return "-" + toTime(-seconds);
return new Date(seconds * 1000).toISOString().substr(11, 8);
}
console.log(toTime(540));
console.log(toTime(-2820));Just test
const convert = secs => {
const sign = secs < 0
const hhmmss = new Date(Math.abs(secs) * 1000).toISOString().substr(11, 8);
return sign ? '-' + hhmmss : hhmmss
}
console.log(convert(540));
console.log(convert(-2820));
