Declare two textures, the texture you want the thing to have, then a
perfectly clear texture:

#declare basetexture = texture {pigment {radial frequency 8}
finish{specular 1}}
#declare cleartexture = texture { pigment { rgbt 1 } }
#declare anim_clock = xxx; // 0 to 1
sphere { 0.0, 1
         texture { average
                   texture_map { [(1- anim_clock) basetexture ]
                                 [(anim_clock) cleartexture ] } } }

as anim_clock goes from 0 to 1, the object will fade.
