The number you are returning is the number of seconds since January 1, 1970 12:00:00 AM GMT. To get the time portion (as you indicated in your comments), you'd first need to convert it to a date, and then just take the time portion of that date.

For example:

var unixTimestamp = localStorage.getItem("time"); // 1661342806 
var d = new Date(unixTimestamp * 1000).toLocaleTimeString();
