Not sure how your scene is  structured but one thing that comes to mind
would be to put all your objects into a union like


union {
   sphere ...
   triangle ...
    //  up to here are your objects

   rotate  clock * y

}
Read the part about animation in the manual of povray. There is a clock
variable that can be set and if you use povray's animation feature this
variable is increased
with each new frame.
Of course one could mention that there are macromolecular graphics
programs that support animation with povray in one form or other.
Hope this helps.

 Lothar.
