I treat ntp service as restart when its starting time is less than 10sec.
Correct me if it is not reasonable. #Closed

I am not sure how stable is the 10s hard-coded value. If you know exactly when the service is restarted (by your test script), you can take a timestamp before the restarting and use it to check the etimes.

The restart is embedded into GCU post-check. Seems hard to find the exact time.
10s should be enough. Usually, the elapsed time is just 1 sec.
I am a little worried that the service process is not up if the check is too soon.
