Usualy, any variable containing "clock", with any form of
capitalisation, refer to the clock built in variable and is related to
animations.
Most of the case, you'll find something like:
#declare sClock = clock*Something;
or
#declare sClock = clock*Something+SomethingElse;
It can also be set to some user defined value. When used with splines,
it's usualy used to pick a specific point along the spline.
