FTS Report on DOY 141

I.  The following are clock offsets, in microseconds between the clocks
at each DSN complex and each complex relative to UTC(NIST).  The offset
is a mean of readings using several GPS space vehicles in common view.

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
& There were not enough common viewed SV between SPC 10 and SPC 60 on DOY 131 (MJD 54231)
% SPC 10 complex-wide data outage and UPS problems on DOY 137 (MJD 54237) wiped out previously accumulated data. 
$ Time step was introduced at SPC 10 after the receiver came back up on DOY 138 (MJD 54238).
