I have two sample unix timestamps that I'm trying to find the difference for in hours/minutes/seconds. One is a current time from TypeScript and one is an expiration time within 24 hours after. I just want to print out the time left until expiration.How do I go about this in TypeScript and Node?
current_time = 1633115367891
exp_time = 01633201203
You can convert unix timestamp to milliseconds timestamp and take their delta. Then convert the delta to hh:mm:ss format.
const current_time = 1633115367891,
exp_time = 1633201203,
diff = (exp_time * 1000) - current_time,
formatTime = (ms) => {
const seconds = Math.floor((ms / 1000) % 60);
const minutes = Math.floor((ms / 1000 / 60) % 60);
const hours = Math.floor((ms / 1000 / 3600) % 24);
return [hours, minutes, seconds].map(v => String(v).padStart(2,0)).join(':');
}
console.log(formatTime(diff));
