DOY			FTS Report on DOY 170

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 (54991 to 55000):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation

NOTE:	As of DOY 135 (MJD 54966) SPC 10 data are from the newly installed multichannel receiver commonview with NIST. 
	As of DOY 68 (MJD 54899) data from (SPC40-SPC10) and (SPC60-SPC10) are derived from direct subtraction.
	As of DOY 158 (MJD 54989) SPC 40 TTR5 single-channel receiver failed. It came back shortly after station 			personnel power cycled it but failed again soon after, and has been dead since.
