%X Stationary axisymmetric spacetimes containing a pair of oppositelyrotating
periodically-intersecting circular geodesics allow the study of various socalled
'clock effects' by comparing either observer or geodesic proper time periods
of orbital circuits defined by the observer or the geodesic crossing points. This can
be extended from a comparison of clocks to a comparison of parallel transported
vectors, leading to the study of special elements of the spacetime holonomy group.
The band of holonomy invariance found for a dense subset of special geodesic
orbits outside a certain radius in the static case does not exist in the nonstatic
case. In the Kerr spacetime the dimensionless frequencies associated with parallel
transport rotations can be expressed as ratios of the proper and average coordinate
periods of the circular geodesics.
