6.2 NTP Configuration

FIGURE 6.2 Operation Diagram when External NTP Server is used (When three NTP servers are used)
Only one NTP server is specified: in that case, when it is not possible to communicate with the NTP server which is
specified by the NTP client, since other synchronous object does not exist, NTP server is disabled. NTP client cannot do
the time correction according to NTP within the period in which communication with the NTP server is restored. As a result,
time is recorded with the system clock accuracy. Since there is an individual difference in the accuracy of the system clock,
when time correction according to NTP is not possible, time gap between the systems is enlarged, and problems might be
caused in the middleware or in the application.
Remark
NTP server 1-NTP server 3 are the NTP servers having high accuracy of time in internet or in intranet.
