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

In chrome you can open the console with F12 and test the following code:

var date = new Date().getTime()
console.debug('date: ' + date);

if (Date.now() < date)
    console.debug('ko');
else
    console.debug('ok');
