/**
* Gets the clock's Drift in nanoseconds per second.
*
+ * <p>This value is the instantaneous time-derivative of the value provided by
+ * {@link #getBiasNanos()}.
+ *
* <p>A positive value indicates that the frequency is higher than the nominal (e.g. GPS master
* clock) frequency. The error estimate for this reported drift is
* {@link #getDriftUncertaintyNanosPerSecond()}.
