This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
    
1. How does your display js variables code look? 2. How does your final javascript work after compiling? (use View Source). – h2ooooooo Jun 4 '13 at 8:51

Is this the actual code you're using? It should be noted that you're setting the variable $m to both month and minute, so it will have the value of the minute (30) when you assign it to the javascript variables – Pudge601 Jun 4 '13 at 9:00
    
here is my display block <td align="center" ><div class="numbers" id="dmin"></div></td> <td align="center" ><div class="numbers" id="dsec"></div></td> ..... document.getElementById('dmin').innerHTML=dmin; document.getElementById('dsec').innerHTML=dsec; – user2372177 Jun 4 '13 at 9:12

<script type="text/javascript">

var year=parseInt(year);  // try this
var month=parseInt(<?php echo $mo;?>); // or this         
var day=parseInt(<?php echo $da;?>);           
var hour=parseInt(<?php echo $hr;?>);          
var minute=parseInt(<?php echo $mi;?>); 
....
// displaying js variables....
....
<script>
</body

This should probably work

To convert a string to int in PHP use intval

But in your case you don't need to convert, you can just echo it to javascript.

$y = "2013";
$m = "06";

...

var year=<?php echo $y;?>;
var month=<?php echo $m;?>;

Will output

var year=2013;
var month=06;

Typecasting as an int works just as well as intval. The only difference is that intval can convert to a different base. Casting as an int is also faster. – h2ooooooo Jun 4 '13 at 8:55
