transformation reference epoch

epoch at which the parameter values of a time-specific coordinate transformation are valid

Note to entry: Coordinates first need to be propagated to this epoch before the coordinate transformation is applied. This is in contrast to a parameter reference epoch where the transformation parameter values first need to be propagated to the epoch of the coordinates before the coordinate transformation is applied.
