[Isocops] IBEX Goat Herder for 27 Aug 21 (Spacecraft Clock Issue)

[Perry, Timothy E [US] (SP)]

All,
    The AUWA01 pass @00:30 I noticed that the spacecraft time was incorrect. The clock was reporting 1970/01/01 00:00:00. It was not incrementing. The stored commands were executing on time and the ACS time  was correct. All the telemetry points had the timestamp 1970/01/01 00:00:00. Hoping that that it was just a ground system issue post SSR dump I instructed SSC to fail over to string 1 from string 2. I saw the same timestamp issue on string 1. I noticed  that in the playback post pass that the time stopped incrementing @2021:236:07:50:04 (24 Aug21). No commands were executing at that time.  Overall the spacecraft looks nominal.  The next planned pass is in the morning USHI01 @16:00 - 17:00 gmt.
