When I am using this console page for Stackexchange API search, I can see it is generating a time-stamp in this format

/2.1/search----fromdate=1380326400&todate=1380412800-------site=stackoverflow

What is this date format  ? how to convert to this time stamp from

var date = new Date().getTime();

I got the soecification from this doc , but I didn't get any method to convert  , it is not just eliminating the millisecond values by dividing with 1000
