Pass Datetime/Timestamp from PHP to Javascript by echo

Question

How can I pass a datetime/timestamp from PHP to javascript. The following does not appear to work:

startLive = new Date(<?php echo date("U", strtotime($start_date)); ?>);

Please provide more information such as Where are you writing this line ? Within a Jvascript script tag or somewhere else, if you can share a little more code, I might be able to guide you better. — Beenish Khan, Apr 19 '12 at 17:04
@ChasingDeath: Sure, `date` returns a string in PHP, but specifying the format as "U", really it's an integer value (even though the variable type is `string`). Javascript still takes it as an integer, so that's not the problem. Really, I think the only problem here is that he needs to multiply it by 1000 to convert it to milliseconds. — Travesty3, Apr 19 '12 at 17:12

Try this:

startLive = new Date(<?php echo strtotime($start_date)*1000; ?>);

Explanation:

PHP's strtotime function returns a Unix timestamp (seconds since 1-1-1970 at midnight).

Javascript's Date() function can be instantiated by specifying milliseconds since 1-1-1970 at midnight.

So multiply seconds by 1000 and you get milliseconds, which you can use in Javascript.

I think that very simple and more universal solution would be

var dateTime = <?php echo date('c', strtotime($yourDateTime)) ?>;

You can use this:

startLive = new Date("<?php echo date("F d, Y G:i:s",strtotime($start_date)); ?>");

this will sort your problem
