Why new Date().getTime() returns too much "0" in javascript

Question

I'm trying to get a timestamp from a date in javascript but new Date(2013, 03, 17).getTime() return 1366149600000 which is wrong (1981-2-2 23:11:12). If I remove the three last zeros, I get the good date.

Where the problem come from ?

Answer 1

it returns milliseconds, unix timestamp are in seconds hence your need to remove the last 3 digits

Answer 2

As per Damien's answer, you will get milliseconds so basically you have to divide the .getTime() result per 1000

getTime() / 1000 => good unixtimestamp
