Add the components where the time will be printed on the HTML page:

<p id="standardTime"></p>
<p id="customTime"></p>

The following functions handle displaying the time:

/**
 * Displays the time in both standard (received from the system) and custom
 * (manually built) formats.
 */
function displayTime() {
    // Get current date info
    var today = new Date();
 
    // Standard format
    document.getElementById("standardTime").innerHTML = today;
 
    // Custom format
    var y = today.getFullYear();
    var m = today.getMonth() + 1;  // Starts from 0
    var d = today.getDate();
    var hh = today.getHours();
    var mm = today.getMinutes();
    var ss = today.getSeconds();
 
    // Add a zero in front of numbers < 10
    m = padTime(m);
    d = padTime(d);
    mm = padTime(mm);
    ss = padTime(ss);
 
    var result = y + "-" + m + "-" + d + " " +
                 weekDays[today.getDay()] + " " +
                 hh + ":" + mm + ":" + ss;
 
    document.getElementById("customTime").innerHTML = result;
}
 
/**
 * If time is represented by one digit, add '0' in front of it.
 * @param i the number to convert to two digits
 * @return a string representing the number in two or more digits
 */
function padTime(i) {
    if (i < 10) {
        i = "0" + i;
    }
    return i;
}

Also add the call to setInterval which in this case updates the time every 0.5 seconds.

setInterval("displayTime()", 500);
displayTime();

Postconditions

Time is displayed on the HTML page in both standard (received from the system) and custom (manually built) formats.
