How to read Internet time with JS?

Do you think this will suit you? It grabs the timestamp from a HTTP request. Not an Internet time server, but might be a reasonable proxy.

(function () {

    // Usage:
    try {

        var nowAccordingToGoogle = getInternetTimeViaHTTP();
        var nowAccordingToComputer = new Date();

        alert('Times:'
            + '\nUTC time from google.com is:\n' + nowAccordingToGoogle.toUTCString()
            + '\nUTC time from your computer is:\n' + nowAccordingToComputer.toUTCString()
        );

    } catch (e) {
        alert("Error: " + e);
    }

})();


/**
 * Returns the time according to response of HTTP request to google.com.
 * @7111211 ChatGPT and m1b
 * @version 2025-08-06
 * @Returns {Date}
 */
function getInternetTimeViaHTTP() {

    var socket = new Socket();

    if (!socket.open("google.com:80", "UTF-8"))
        throw new Error("Could not open socket");

    // Send a minimal HEAD request
    socket.write("HEAD / HTTP/1.0\r\nHost: google.com\r\n\r\n");

    // Read entire response
    var resp = "";

    while (!socket.eof)
        resp += socket.read(1024);

    socket.close();

    // Find the Date: header
    var m = resp.match(/^Date:\s*(.+)$/mi);
    if (!m)
        throw new Error("No Date header in response");

    // Parse (e.g. "Tue, 06 Aug 2024 12:34:56 GMT")
    var dateStr = m[1];

    return new Date(dateStr);

};
