They add the following commands:

   -anewer
   -cnewer
   -mnewer
   -okdir
   -newer[acm][acmt]

 With it, you can form queries like

     find . -newerct '1 minute ago' -print

 As an extra bonus, the program is ANSI-fied - the original version
 relies on some obscure features of K&R C.

(This PR was submitted in 1999, and the submittor has kept the patch
updated ever since, hats off for him guys, and how about you close a PR ??)
