Date, time & validation in php form

Hi,

With a bit of help from a tutorial I have created a form in flash using php. However, I two things are left to complete it:

I want the message to state the time and date the form was sent… I have been trying several codes but doesn’t work.

And I have to validate the form too… I haven’t still looked at that but if anybody can suggest a tutorial I would very much appreciate it.

Thanks,
