func SntpDrift 

func SntpDrift(measurements int) (time.Duration, error)

SntpDrift does a naive time resolution against an NTP server and returns the measured drift. This method uses the simple version of NTP. It's not precise but should be fine for these purposes.

Note, it executes two extra measurements compared to the number of requested ones to be able to discard the two extremes as outliers.
