a. If bit 0 is cleared, the residual was used to attempt to compute the clock offset.
If bit 0 is set, one or more of bits 3-31 are set indicating the reason(s) the residual
was excluded from the clock solution.
Bit 0 is not set at the same time as bits 1 or 2.
Residual could not be computed or was
excluded from the clock offset computation
