synchronize with you. It is important that you configure several servers for
redundancy.
Peers
If you configure machines as peers, they will listen to each other and move
toward a common time. Peers are considered equal with each other as
opposed to servers, which are considered "masters". It is important that you
configure several peers so that they can decide on the right time.
NTP Reference Clock
You can turn on the NTP reference clock if you wish to have your server
configured as a source of time information. In this mode, it is recommended
that you keep the stratum value at its default (1). The stratum value tells how
far away the NTP reference clock is from a valid time source.
Note
The time server begins to provide time information 5 minutes after it is
configured.
