If +/- 1 Second in ~17+ minutes (or so) is acceptable to the OP.

That would probably also be fine for many leaf client end users.

 I doubt most astronomical, real time high frequency trading,
   or maybe even other IT uses of timestamps would be very
   happy with uncontrolled drifting apart for at least
   a quarter of an hour and then jumping to the correct
   time and continuing uncontrolled drifting apart again.
