How can I get seconds since epoch in Javascript?

Question

On Unix, I can run date \'+%s\' to get the amount of seconds since epoch. But I need to query that in a browser front-end, not back-end.

Is there a way

Answer 1

EPOCH means time from 01 January 1970
var date = new Date();
Following line will return the number of milliseconds from 01 Jaunary 1970
var ms = date.getTime();
Following line will convert milliseconds to seconds
var seconds = Math.floor(ms/1000);
console.log("Seconds since epoch =",seconds);
