gpsTimeFigureOfMerit

The Time Figure of Merit (TFOM) value ranges from 3 to 9 and indicates
the current estimate of the worst case time error.  It is a logarithmic
scale, with each increment indicating a tenfold increase in the worst case
time error boundaries.  The scale is referenced to a worst case time error
of 100 picoseconds, equivalent to a TFOM of zero.  During normal locked
operation the TFOM is 3 and implies a worst case time error of 100 nanoseconds.
          
During periods of signal loss, the GPS sub-system will compute an
extrapolated worst case time error.  One hour after the worst case time error
has reached the value equivalent to a TFOM of TFOM Fault Level, the NTP server
will cease to send stratum 1 reply packets and an Alarm LED will be energized.
