IE Date.Parse() returns NaN

Question

I am trying to parse this string

"2017-06-01 11:22:20.683"

It is working just fine in Firefox, but return NaN in IE 11
Unfortunately I am unable to modify the source string since its coming from a legacy system.

function myFunction() {
    var d = Date.parse("2017-06-01 11:22:20.683");
    document.getElementById("demo").innerHTML = d;
}

<p id="demo"></p>
<button onclick="myFunction()">Try it</button>

Here is the simpliest solution:

function myFunction(dateString) {
    var str = dateString.replace(/^(.*-[0-9][0-9])(\ )([0-9][0-9]\:.*$)/, '$1T$3')
    var d = Date.parse(str);
    document.getElementById("demo").innerHTML = d;
}
