Javascript new Date not working in IE (Invalid Date)

I have a script that works fine in chrome but cannot convert the date in IE and gives an invalid date error.
I know it is something to do with the way the date is formatted that IE doesn't like.

I am passsing this date in Chrome from a label on a page (2015-05-27 03:00:00 PM)

               var ASPDate = document.getElementById('<%=LabelCutoffTime.ClientID%>').innerText;

               var ASPfutureDate = new Date(ASPDate);
