I doubt you will find this sort of information in any spec sheet on a basic

answer is going to be “try it and see”.
Yes - agreed. I was hoping someone would have tried it already on the
GPS 16 HVS unit as has been done for a different unit...

...which returns about 0.1 ms drift in phase over 15 minutes.
I'll do a test as suggested elsewhere between a locked GPS and one which
is in invalid fix condition.
If this is for some sort of large scale system, that may not
be the right way to do it……
No - it's not a large scale system. I want to time-stamp my Vela pulsar
data. Just recently I detected a glitch in the pulsar (the first
amateur radio astronomer to ever do so with any pulsar AFAIK)...

The professional guys were impressed with my data, but slightly
disappointed it didn't have accurate time-stamping. I am working to
rectify that for the next glitch.
