NTP isn't going to be the only "ripple".
Most of the "brand name" GPS NTP solutions have a clock
with is more than stable enough to survive without GPS
lock for 45 minutes(*). Some of the more expensive units with
temperature controlled oscillators have hold times in the
many weeks. My guess is that the NTP ripples will be
limited to those NTP servers just (or recently) booted
which have not yet achieved a stable clock state.

(*) This presumes that this test results in loss of signal
lock, and not intentionally injected false information.
