3. Time Synchronization
After booting, NTP uses slewing to achieve synchronization by making small and frequent changes to
the router hardware clock. If the reference server's clock differs from the local clock by more than 1000
seconds, the NTP daemon decides that a major problem has occurred and terminates.

3.2. Configuring Time Synchronization

To configure time synchronization, configure the following items:
• set the system time and date. See
• set the system timezone. See
• set the local time settings. See
• add remote NTP servers. You can add remote NTP servers with or without authentication. See
Section 3.2.4, "Configuring NTP
• set the NTP server restrictions. See
• configure an NTP server using Multicast or Broadcast. See
using Multicast or
• configure an NTP client using Multicast. See
Multicast".
