Why is that?

I would have guessed that a GPSDO would average over many GPS pulses thus 
reducing the noise.

Is it something like GPSDOs are normally designed for good frequency rather 
than good time, so when they find the time is off, they use a small frequency 
offset for a long time to correct rather than a big frequency offset for a 
short time?

Are there any GPSDOs designed for good time?  Or any with parameters that can 
be tweaked to provide good time?
