That Leap Second is coming! This may work for most UCS setups. Going to lab test this. Also going to figure a way to do same from UCS Central.
From documentation “If the UCS Domains are registered to a UCS Central instance (and resolving Time/Date from Central), the script will set Policy resolution for Date/Time back to “Local” and then remove each Local NTP Server Entry”. Very cool. Wondering if Central can just be set to “no ntp servers”?
