the clock variable defaults to 0..1,
this can be changed in the ini files
or with command line commands,
if you've done that great, otherwise use 1/5 instead...

After holding still you want the
camera to move for 1/5 of the animation.
So just set up another variable for clock
durring that time...

#else
   #local My_clock = clock-1/5;
or
  #local My_clock = clock - 1;

This while loop executes the whole loop, but why?
just leave that out, the animation loop will re-parse
the whole scene for every frame with a different
clock value.

Y an Z have the same value every time...
try something like...
#local CLOC = vrotate(<0,0.75,0>;90*My_clock*y)+<0,-2.75,0>;
camera {
   location CLOC
   look_at <0,0,0>
}

You might also look into using a spline, that might make lining
up the start and stop of your movements line up easier
if you decide to change it later.
