is it possible to create a jQuery function so that it gets current date and time? I\'ve been looking around documentation but haven\'t found anything so far...

@nickf's correct. However, to be a little more precise:
```
// if you try to print it, it will return something like:
// Sat Mar 21 2009 20:13:07 GMT-0400 (Eastern Daylight Time)
// This time comes from the user's machine.
var myDate = new Date();
```
So if you want to display it as mm/dd/yyyy, you would do this:
```
var displayDate = (myDate.getMonth()+1) + '/' + (myDate.getDate()) + '/' + myDate.getFullYear();
```
Check out the full reference of the Date object. Unfortunately it is not nearly as nice to print out various formats as it is with other server-side languages. For this reason there-are-many-functions available in the wild.

Yes, it is possible:
```
jQuery.now()
```
or simply
```
$.now()
```
see jQuery Documentation for jQuery.now()

You don't need jquery to do that, just javascript. For example, you can do a timer using this:

<body onload="clock();">

<script type="text/javascript">
function clock() {
   var now = new Date();
   var outStr = now.getHours()+':'+now.getMinutes()+':'+now.getSeconds();
   document.getElementById('clockDiv').innerHTML=outStr;
   setTimeout('clock()',1000);
}
clock();
</script>   

<div id="clockDiv"></div>

</body>

Annoyingly Javascript's date.getSeconds() et al will not pad the result with zeros 11:0:0 instead of 11:00:00.

So I like to use
```
date.toLocaleTimestring()
```
Which renders 11:00:00 AM. Just beware when using the extra options, some browsers don't support them (Safari)

  var outHour = now.getHours();
  if (outHour >12){newHour = outHour-12;outHour = newHour;}
  if(outHour<10){document.getElementById('HourDiv').innerHTML="0"+outHour;}
  else{document.getElementById('HourDiv').innerHTML=outHour;}

  var outMin = now.getMinutes();
  if(outMin<10){document.getElementById('MinutDiv').innerHTML="0"+outMin;}
  else{document.getElementById('MinutDiv').innerHTML=outMin;}

  var outSec = now.getSeconds();
  if(outSec<10){document.getElementById('SecDiv').innerHTML="0"+outSec;}

this is my way :

    <script type="text/javascript">
$(document).ready(function() {
    setInterval(function(){currentTime("#idTimeField")}, 500);
});
function currentTime(field) {
    var now = new Date();
    now = now.getHours() + ':' + now.getMinutes() + ':' + now.getSeconds();
    $(field).val(now);
}

it's not maybe the best but do the work :)
