This article may be dated, but it should still do the trick http://www.tizag.com/javascriptT/javascriptdate.php

To return the current date, you can use something like:

var currentTime = new Date()

var month = currentTime.getMonth() + 1

var day = currentTime.getDate()

var year = currentTime.getFullYear()

document.write(month + / + day + / + year)

And to return the time you can use something like:

var currentTime = new Date()

var hours = currentTime.getHours()

var minutes = currentTime.getMinutes()

if (minutes < 10){

minutes = 0 + minutes

}

document.write(hours + : + minutes +  )

if(hours > 11){

document.write(PM)

} else {

document.write(AM)

}​
