Ajax Chat Command To Add Time Of Post?

[PGTibs]

I've got a small ajax simple chat on my website that consists of 3 webpages. I have found where i want to add the time but don't know what command to use that will show the current time of when it was posted and not the time it is at the moment the user is viewing the page?

 

E.g. the time the message is sent other than the time it currently is.

 

Properties File, contains text line.      w.php
