The system time of the replication service needs to be consistent with the system time of AOC to ensure proper functioning of the replication service. You need to confirm whether NTP servers have been configured for AOC by navigating to the AOC time page in the System configuration page of AOC. If not configured, refer to the Configuring NTP servers section in AOC User Guide for configuration instructions. Once AOC has configured an NTP server, the replication service will automatically synchronize its system time with it.
