JavaScript Unix timestamp?

[grippat]

How would I use JavaScript to get the current Unix timestamp?

[Ingolme]

You can try this:a = new Date()var d = Number(Date.UTC(a.getFullYear(),a.getMonth(),a.getDate(),a.getHours(),a.getMinutes(),a.getSeconds(),0));d = d/1000;// d would be the Unix timestamp for this moment.

A slightly shorter way to achieve the same thing would be:

Math.floor(new Date().getTime()/1000)

How about:new Date().valueOf()

[Pollux]

valueOf() uses the getTime() implementation internally which means that as with getTime() it returns a timestamp which is ms since the epoch, however the unix timestamp is seconds since the epoch. So we need to divide by 1000 and then perform a round to get an integer.
