Hello Daniel,   You are correct, setting and NTP server will not impact production environment.  One of the features of the Group Lead member is to be the master clock for all other members.    Typically problems come in with you are using AD authentication.  If the time drifts too far, AD logins will fail at the AD Domain Controller.   iSCSI operations are not affected.   Regards, Don
