I concur.  Here is a simple code fragment that might help.  I'm sure
I stole it from someone else so I can't take credit, but it gives you
a starting point for using the clock as a phase modifier.  Looking at
the code again I can't think of a worse example, but you work with
what you have, right?  :-)

#declare Sea = plane {
    y, 0
    texture {
        T_Silver_1C
        normal {
            average
            normal_map {
                [ ripples 0.05 frequency 2 scale 0.05 translate <0, 0,
100000> phase ( clock * -3 ) ]
                [ ripples 0.15 frequency 3 scale 0.008 translate <0, 0,
10000> phase -clock ]
                [ waves 0.15 frequency 2 scale 0.05 translate <0, 0, 10000>
phase -clock ]
                [ wrinkles 0.25 scale 0.01 ]
                [ wrinkles 0.001 ]
            }
        }
    }
}
