  3. Convert a Unix timestamp to time in JavaScript

I am storing time in a MySQL database as a Unix timestamp and that gets sent to some JavaScript code. How would I get just the time out of it?

For example, in HH/MM/SS format.

First answer

// 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);

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

Second answer

JavaScript works in milliseconds, so you’ll first have to convert the UNIX timestamp from seconds to milliseconds.

var date = new Date(UNIX_Timestamp * 1000);
// Manipulate JavaScript Date object here...

Third answer

I’m partial to Jacob Wright’s Date.format() library, which implements JavaScript date formatting in the style of PHP’s date() function.

new Date(unix_timestamp * 1000).format('h:i:s')
