Time Sync
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 varies with each other or with the
correct time and this can cause, firewall packet filtering schedule processes
to fail, security to be compromised, or system log exposures with wrong
data.
Click TIME SYNC.
There are two synchronization modes:
Sample Network Time Protocol (SNTP)
and synchronization with PC. For
synchronization with PC, select Sync with
PC. The gateway will synchronize the
time with the connecting PC.
SNTP is the acronym for Simple Network
Time Protocol, which is an adaptation of
the Network Time Protocol (NTP) used to
synchronize computer clocks in the
Internet. SNTP can be used when the
ultimate performance of the full NTP
implementation is required.
For SNTP, select SNTP v4.0.
SNTP service: Enable
Time Server: Any of the time servers around the world can be used but it is suggested to use a
time server physically nearby.
Time Zone: you have to choose the right time zone.
