Date and Time Settings
The Date and Time page provides information about the current system time and date. The settings may be updated through the international time and
date servers.
Time is used to set the local time (hour, minute).
Date is used to set the date (month, day, year).
Enable Simple Network Time Protocol Server
enables the
SNTP (Simple Network Time Protocol) server on QX Gateway,
thus QX Gateway becomes the timeserver for its LAN.
Enable Simple Network Time Protocol Client enables the
SNTP client on the QX Gateway, thus QX Gateway becomes a
client to an external timeserver. A checkbox disables Date and
Time drop down lists and enables the following parameters:
The SNTP Servers table lists all defined NTP Servers.
The Add functional button opens an Add NTP Server page
where a new NTP server can be defined. This page offers the
NTP Server radio buttons that are used to choose between a
manual and a predefined NTP server.
• Manual requires the NTP server’s FQDN (Full Qualified
Domain Name) or its IP address.
• Predefined is used to select the NTP server’s host
address from the drop down list, where the most
common NTP servers are listed.
Fig.II- 10: Date and Time Settings page
The
Move Up
and
Move Down
functional buttons are used to
sort NTP servers in the order they need to be accessed. If the
NTP server in the first position of the SNTP Servers table does
not answer, NTP server in the next position will try to be
reached.
Please Note: You can add another NTP server to the list if the
defined NTP servers are not functional (for example, QX's
date/time is not being updated automatically).
Polling Interval indicates the time interval for the periodical
synchronization between the timeserver and QX Gateway. It
counts in hours.

Attention: Date and Time Settings will be reset if QX Gateway has lost power.
