SHB/MFRSR/C1 - Cosine solar zenith angle incorrect

The cosine of the solar zenith angle does not appear to be correct in the netCDF files.  
This variable is shifted in time by about two hours with respect to the other variables; 
the time registration of the other variables looks fine.  Why only one variable got 
shifted is a mystery, but at least the important, radiometric data appear not to be shifted.
