Chrome cannot convert date string to date in format YYYY/MM/DD PM hh:mm - google-chrome

Question

I think Chrome is most flexible browser but it is not working in below case:
newrecorddate = "2015/10/20 PM 06:09"
var d = new Date(newrecorddate);
console.log("d="+d);
In IE11 the date (d) is returned successfully. In Chrome "Invalid Date" is returned. How can I workaround it?
UPDATE:
Dai's code actually solve the problem so it is marked as answer. Here is the code I use:
var r = /(\d{4})\/(\d{1,2})\/(\d{1,2}) (PM|AM) (\d{2})\:(\d{2})/;
if( newRecordDate.match( r ) ) {
var ymd = newRecordDate.split(" ")[0];
var tt = newRecordDate.split(" ")[1];
var tod = newRecordDate.split(" ")[2];
var d = new Date( ymd + " " + tod + " " + tt );
}
return d;

(Disclaimer: I worked on Chakra, Microsoft's JavaScript engine)
ECMAScript's specification does not list the formats that Date's constructor must successfully parse, in practice most implementations will generally successfully read almost every non-ambiguous format available, however the format you're using, YYYY/MM/dd tt HH:mm is not a format seen in reality (the tt is in the middle instead at the end). A good heuristic implementation might be able to guess it but it helps to not have to guess or depend on any feature support not present in the language's specification.
You'll have to parse the date yourself, reformat it, and pass that into Date's constructor, fortunately regex makes this easy:
var r = /(\d{4})/(\d{2})/(\d{2}) (PM|AM) (\d{2})\:(\d{2})/;
if( r.match( newRecordDate ) ) {
var ymd = newRecordDate.substr( 0, 10 ); // note substr instead of substring
var tt = newRecordDate.substr( 11, 2 );
var tod = newRecordDate.substr( 14, 5 );
var d = new Date( ymd + " " + tod + " " + tt );
}
That should work. Untested though.
