[edit] Source

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();

[edit] Postconditions

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

[edit] Supplementary material
