Note:
• If a time difference is to be corrected by NTP time synchronization
that is supported by LPAR manager firmware version 01-60 or later
and takes place at a regular interval of 15 minutes, and if a time
difference of more than 60 seconds occurs, any subsequent attempts
to perform the NTP time synchronization will be canceled. If this
phenomenon occurs, review the LP system log message that includes
"An abnormal time difference was detected", and then take action as
described in the message.
• [No time synchronization of LPAR manager system time by NTP server]
