Doubtful of the last paragraph: What kind of clock oscillator 'learns' to keep better time by being adjusted from a better source? A normal crystal doesn't have any memory effect AFAIK.
In a typical real life scenario where the GPS / antenna malfunctions, your server clock will just slowly.. drift.. I.e. the crystal runs a bit too fast or a bit too slow.
