How to convert a Unix timestamp to time in JavaScript

Javascript Oct 30, 2022

Requirement:
We have stored time in a MySQL database as a Unix timestamp and that gets sent to some JavaScript code. Now we want to extract only time from it.

i.e. in HH/MM/SS format.

Solution:

let unix_timestamp = 1549312452
// Create a new JavaScript Date object based on the timestamp
// multiplied by 1000 so that the argument is in milliseconds, not seconds.
var date = new Date(unix_timestamp * 1000);
// Hours part from the timestamp
var hours = date.getHours();
// Minutes part from the timestamp
var minutes = "0" + date.getMinutes();
// Seconds part from the timestamp
var seconds = "0" + date.getSeconds();

// Will display time in 10:30:23 format
var formattedTime = hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);

console.log(formattedTime);

Final Words:
For more information regarding the Date object, please refer to MDN or the ECMAScript 5 specification.

Thanks!
