How to Get the Time from a Unix Timestamp in JavaScript?

Getting Time from Unix Timestamp in JavaScript

In web applications, it's common to encounter timestamps in Unix format, which represent time in seconds since January 1st, 1970. JavaScript provides a way to convert these timestamps into a user-friendly time format.

To retrieve just the time portion from a Unix timestamp, you can use the following steps:

1. Create a JavaScript Date object based on the timestamp provided in milliseconds. To do this, multiply the timestamp by 1000, as Date objects work with milliseconds.
2. Extract the hours, minutes, and seconds from the Date object.
3. Format the time in the desired format (e.g., HH/MM/SS).

Example Code:

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);
