If there is no external server, and instead the network has a node configured with the
command:
ntp master , the following commands will work as expected:
The clock set command may also be used prior to configuring an external NTP server to
get the network roughly up to the correct time, so that NTP will synchronize faster.
The primary function of NTP within an AMF network is to ensure that time and date
stamps on backups are consistent across member nodes within the backup. This is
particularly important in an AMF network that has multiple AMF master nodes, to ensure
that node recovery is performed with the most up to date backup.
