2 clock status
Clock model status (not including current measurement
data). See
Table 36 on Page 79.
Enum 4 H
3 offset
Receiver clock offset, in seconds from GPS time. A positive
offset implies that the receiver clock is ahead of GPS time.
To derive GPS time, use the following formula:
GPS time = receiver time - offset
