获取文件最后修改属性的最佳方法

What would be the best way to get the "last modified" attribute from a file NOT on the web server. My purpose is to display the time stamps of specific network files in a web page. All the JavaScript references I have found are for the current file, or from the web server. I have found references for browsing to, drag-and-drop, etc. But I would like to read the file attribute from the original location. Is this even possible??

EDIT: So now that I have a batch file to create the text file on the web server, how do I get that data into an array so I can display it properly? The data is correct, but it is one long string.

This is my code:

<html>
<head>
    <script type="text/javascript">
        function getStatus() {
            var xhttp = new XMLHttpRequest();
            xhttp.onreadystatechange = function () {
                if (xhttp.readyState == 4 && xhttp.status == 200) {
                    document.getElementById("backupStatus").innerHTML = xhttp.responseText;
                }
            };
            xhttp.open("GET", "file.txt", true);
            xhttp.send();
        }
    </script>
</head>
<body>
    <button type="button" onclick="getStatus()">Get QNAP Backup Status</button>
    <ul id="backupStatus">

    </ul>
</body>
</html>

This is my output:

@ECHO 4/13/2016 @FREEMAN1 4/13/2016 @FREEMAN02 4/13/2016 @FREEMAN03 4/7/2016 @FREEMAN4 4/7/2016 @FREEMAN5 4/7/2016 @HR10 4/13/2016 @ACCOUNTING20 4/12/2016 @IT01 4/13/2016 @PROD20 4/12/2016 @UPS10 4/13/2016

javascript can't go out and read files on a user's computer. You'd need to read this information on a server and load it in to the page, or via an ajax call.
