machine placement. A time server placed higher in the tree (lower stratum number), provides a
higher likelihood of agreement with the UTC time standard.
You should use the security features of NTP to avoid the accidental or malicious setting of an
incorrect time by using an encrypted authentication mechanism.
NTP has become a standard for internet time synchronization. Most importantly, there are
more than 100000 free NTP time servers in the world.
For setting the IP address of the NTP server using the Web, see
5.4.1
Daylight Saving Time (Summer Time)
You can configure your Gateway to observe the Daylight Saving Time (DST) in your area.
Once configured, whenever the system time is updated using a time server located in a
different time area, it will be automatically corrected with the local DST time offset.
The DST is followed by the U.S. standards. You can have the Gateway advance the clock one
hour at 2:00 a.m. on the first Sunday in April and move back the clock one hour at 2:00 a.m.
on the last Sunday in October. You can also explicitly specify the start and end dates and times
and whether or not the time adjustment recurs every year.
For enabling automatically adjust the internal clock to daylight saving time according to the
local time zone via Web see

Understanding Syslog
The system message logging can save messages in a Syslog server. The system message
logging facility:
•
Provides you with logging information for monitoring and troubleshooting.
•
Allows you to select the
types
of logging information to be captured and the
destination
of
that information.
You can specify which system messages should be executed, based on their severity level (see
). You can monitor system messages by viewing the logs on a Syslog server.
