        Modify the time constant DUT1 (in seconds) and recompute the phases  ac-

        justed afterwards to correct for irregularities for the earth  rotation.
        The  "a  priori"  estimates may be wrong.  Another case is the leap sec-
        onds, if they are introduced asynchronously with the DUT1 constant...
