Hi I have one issue in my Laravel Application.

The issue is that Internet Explorer giving wrong time as compare to firefox or chrome in JavaScript.

My JavaScript Code.

console.log(expDate + ' --> ' + new Date(expDate).getTime() + " --> " + $.now());

Its Output in Firefox.

09/25/18 4:31 PM UTC --> 1537893060000 --> 1537875054235

Output in IE.

09/25/18 4:31 PM UTC --> -1617866940000 --> 1537875062939

Can anyone help me that how to resolve the issue. I want that new Date(expDate).getTime() must give the correct time in all browsers.

Any help will be appreciated.

Thanks
