5.2.8 SNTP

Overview

The Simple Network Time Protocol (SNTP) web page allows you to configure the 
SpeedTouch™ real-time clock.

The page contains two sections:

SNTP Client

As long as the SNTP section is selected, automatic time synchronisation of the 
SpeedTouch™ real-time clock by means of the SpeedTouch™ SNTP client is 
guaranteed (given that NTP servers are configured of course).

The SNTP table allows you to overview and add/delete NTP servers (present on the 
Internet or your local network) to which the SpeedTouch™ real-time clock is able to 
synchronize its time settings with.

To add an NTP server:

Click New (if an entry is currently selected, click Cancel first)

Type the host name or IP address of the NTP server.

Select the NTP version (1, 2, 3, or 4). This information is most likely provided 
with the NTP server's IP address.

Click Apply. 

You can add multiple NTP servers. This ensures that the SpeedTouch™ SNTP client 
will always be able to contact at least one NTP server to synchronize the 
SpeedTouch™ real-time clock with.

Manual

You can manually configure the SpeedTouch™'s real-time clock in case no 
connection to an NTP server is available.

To manually configure the SpeedTouch™ real-time clock:

Type the current Date (day/month/year)

Type the current Time (hours:minutes:seconds in 24-hour clock)

Select the Time Zone suiting your physical regional location.

Select Daylight saving to adjust the SpeedTouch™ real-time clock to daylight 
saving time, if used in your region.

Click Apply to apply the time settings to the SpeedTouch™ real-time clock.

Selecting Manual 

 the SpeedTouch™ SNTP client. As a 

consequence the SpeedTouch™ real-time clock will no longer be 
periodically synchronised with an Internet time server.

You can check the Internet for free accessible real-time NTP servers.
