Use Google to search for: PHP cookie tutorial

Use cookies. Set a cookie (time value). Redirect back
and check the cookie to see if it's there (if it exists).
If not, it means they have cookies disabled, so you will
not accept the comment. If you see the cookie,
then check the value and see if the time has elapsed.
Check it each time they refresh or revisit the page.
When it has elapsed, reset cookie value with a new time.

Note, you can also set and check the same cookie(s) using
Javascripting along with PHP, so you could dynamically display
a running timer that shows the user how much longer they
need to wait until the next allowable comment.
