This is the routine that caculates time from HP secs in MATLAB from SCS file.
dates = datestr(datenum(1601,1,1) + datenum(secs*10000*100e-9/86400))

Ludo says the HP time is from our system.
The 2nd col is GPS time from the SCS. 
JD139 somtime within 1400 these 2 times dirverge. GPS time loses 1 min 10 secs in hr 14 and then ~ 5 mins each hour after that

The reason the data don't match using HP time is I believe that
all the SCS data match it's time, but for some reason weren't written to the file until our HP time. Our time matches the file. This means
that we need to be comparing both times to make sure they are within some limit. If not then we have to set a flag and 
figure out what is going on. Jeff and I may track this down today.

This theory is proven correct by plotting SCS rads using the HP and gpstiems vs PSD rads The one using GPStime compares as expected.

For the period where the times diverge we have to use the SCS GPStime, but figure out how to account for changes in the day and why
gps time is messed up so that it's conversion doesn't make sense. I'm getting mins and secs >60.
