>     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.
