I was setting up the amount of time I wanted the Affiliates module to allow a cookie from the affiliated referred visitor. The default was 0. Your link to the strtotime syntax here, http://us.php.net/strtotime, only made me more confused. After spending about 30 minutes I finally ran across an unrelated post about an unrelated module but luckily found an example of a syntax that would work for me.

Is it possible for you to replace this

"How long should the cookie be valid. Strtotime syntax. The value 0 means "until the browser is closed."

with this?

"How long should the cookie be valid. Strtotime syntax. The value 0 means "until the browser is closed." EXAMPLES of other acceptable formats--now, now + 1 week, Last Thursday, July 10, 2010"
