The clocks themselves are not physically adjusted but numerical corrections (both clock and especially, orbit) for each satellite are updated as often as once every two hours. This is all part of the data stream that's sent down to the receiver.

> The GPS spec implies the satellites have a fixed frequency offset to compensate for relativistic effects.  But do they actually dynamically and/or individually adjust the frequency to adjust for orbit variations and eccentricities?
