7.9.5 SNTP
Time synchronization is an essential element for any business that relies on an IT system. The
reason for this is that these systems all have clocks, which are the source of time for files or
operations they handle. Without time synchronization, time on these systems varies with each
other or with the correct time and this can cause- virtual server schedule processes to fail and
system log exposures with wrong data.
There are two methods to synchronize time, synchronize with PC or SNTPv4. If you choose
synchronize with PC, the router will synchronize with PC’s internal timer. If you choose SNTPv4,
the router will use the protocol to synchronize with the time server. For synchronization the time
server with SNTP v4, needs to configure service, time_server and time_zone. For
synchronization with PC, doesn’t need to configure the above parameters.
