14.13.5 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 that are the source of time for files or operations they handle. Without time
synchronization, time on these systems can vary 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 a PC or SNTPv4. If you choose synchronize with
PC, the router will synchronize with a PC. If you choose SNTPv4, the router will use the protocol to synchronize
with the time server. Synchronization with time server, SNTP v4, needs to configure service, time_server and
time_zone. Synchronization with PC does not require the above parameters.
