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