FTS Report on DOY 257

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.

over the period (53617 to 53626):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
& Frequency adjustment for SPC40 made on DOY 251 (MJD 53621)
