cookies

Thanks for you help in advance.

I am trying to figure out the structure of the cookie file, more specifically i want to be able to determine the expiry time. From the cookies i have created they all appear to be in a standard format. Name, Value, website,followed by 5 numbers and a star. See example below.

name
value
www.website.co.uk/
1536
3041141504
30135951
1632526096
30135949
*

Obviously the expiry time is one of the numbers, the question is which one. From experiments I have determined that the first and fifth number don't seem to change. In a case where i generated three cookies at the same time with a 1000 second time difference i noticed that the fourth number appeared to increase by 2000 suggesting that this has a connection with the expiry time.

Can anyone confirm if i am heading in the right direction? And does any one know how i convert this to a human time and date(preferably in php but any language would give me a starting point)

thanks Jason
