USNO has this to say:
"GPS time is automatically steered to UTC(USNO) on a daily basis to
keep system time within one microsecond of UTC(USNO), but during the
last several years has been within a few hundred nanoseconds."
But, it's often much better. The past week, it's well under 10 ns
difference, the majority of the time.
