All,

   The spacecraft is nominal and the Inertial maneuver was successful. The maestro team suggested using the directive “set Time_Method system”. I tried it and I saw telemetry updating using the system time vs the spacecraft time. This will be a temporary fix for real time data. This does not correct for time drift, but we can create graphs and playback the real-time data if we have an issue. This does not work for backorbit data.
