DateDiff in javascript

Question

User1510859543 posted

Is there an equivalent in javascript to the .net code below to get seconds since 1/1/1970?

DateDiff(DateInterval.Second, #1/1/1970#, DateTime.Now.ToUniversalTime)

As a JavaScript date is the milliseconds since 1/1/1970, you just divide by 1000.

  var seconds = Date.now() / 1000;

The getTime() function of the JavaScript Date() returns the milliseconds since 1/1/1970.  The standard docs cover the details. 

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getTime

Divide by 1,000 to convert millisecond to seconds.

var ms = new Date().getTime(); 
var secs = ms/1000;
console.log(secs);

But does that return Universal time?

Ignore as it looks like it does.
