6.2 The SpeedTouch™ SNTP Client
The SpeedTouch™ Simple Network Time Protocol (SNTP) client allows you to
configure the SpeedTouch™ internal real-time clock (RTC), used for time-critical
operations, for example for online certificates enrolment (IPSec VPN client).
This section shortly describes the configuration and use of the SpeedTouch™ SNTP
client.
Because the RTC does not have an automatic daylight saving switch, you should
update it manually at the correct moments (twice a year).
The RTC
The SpeedTouch™ contains a battery to allow the RTC to maintain the time even
when the device is powered off and restarts. This helps security because even when
the NTP servers are temporarily inaccessible because of a power outage or network
traffic overflow, the SpeedTouch™ has the correct time allowing to correctly
correlate syslog events from various devices and perform correct diagnosis.
You can access the SpeedTouch™ SNTP page via Home > SpeedTouch > SNTP:
By default SNTP is disabled; internal clocking refers to the SpeedTouch™ up time
(i.e. the time passed since last reboot).
