Countdown Timer

[Goose87]

Hey guys,

 

I have the php time() function to display a time, i then do time()+300 to add 5 minutes.  I then minus this value from the time() value to get a number like 230 or so.

 

I then display that to the user in the form:

 

You have 3 minutes 50 seconds until....

 

At the moment it's just a standard message, but I want it to auto click down toward 0 by itself.

 

I have NO knowledge of javascript, so if someone could be as kind to give me as many hints as possible, i'd greatly appreciate it.

 

Thanks
