Does anyone know if Apple has fixed a long-standing problem in Mavericks with time-keeping? I just posted details on this in the Mavericks forum (same title). Short version is that ntp and pacemaker fight over keeping time synchronized, and the user looses. On Snow Leopard I get millisecond accuracy, and on Mavericks it was running tenths of seconds until I implemented a kludge-around (also described in that post). Anyone know if this is fixed in Yosemite?
