How can I convert the (fractional) result of `new Date().getTime() / 1000` into a whole number?

Question

According to this: Get current date/time in seconds

var seconds = new Date().getTime() / 1000; gives you the time in seconds. But the time given is a decimal number. How can I turn it into whole number?

You do Math.round(new Date().getTime() / 1000) or a short (and faster version):

new Date().getTime() / 1000 | 0

Using this binary operator will zero the floating number part of your number (and therefore round it down).

Call Math.round.

Fastest and simplest: Force date to be represented as number by made math operation directly on date object. Parentheses can be ommited where we calling to constructor without arguments

new Date/1000|0  // => 1326184656

+new Date == new Date().getTime() // true

Explanation:

new Date // => Tue Jan 10 2012 09:22:22 GMT+0100 (Central Europe Standard Time)

By apply + operator

+new Date //=> 1326184009580

Round it.

console.log(new Date().getTime() / 1000);
// 1326051145.787
console.log(Math.round(new Date().getTime() / 1000));
// 1326051146

Basic maths!

Thank you. Didn't know of Math.round. – jQuerybeast Jan 08 '12 at 20:38

@LightnessRacesinOrbit: Oh, you again. Here I was thinking your attitude on your first comment above was a once-off. – fulvio Nov 21 '13 at 03:12
@gotnull: Pot, meet kettle. At least I'm trying to teach this OP to do research which will _indisputably help him_ as a skill. You're just writing comments to attack my character. – Lightness Races in Orbit Nov 21 '13 at 10:46
@LightnessRacesinOrbit: Kettle, meet pot. Patronising someone doesn't help at all. I agree with teaching people (OP in this case) to do research, however telling them that Google was registered in 1998 isn't helping at all IMO. Each to their own I guess. – fulvio Nov 22 '13 at 03:09
@gotnull Yes it is. It's bringing the term Google into the conversation. Are you going to stop now? – Lightness Races in Orbit Nov 22 '13 at 09:57
