Enable SNTP
Click this checkbox to enable SNTP, the device will automatically
obtain current time from a SNTP server on the network. You must
Apply and Restart before this change will become effective. SNTP is

Time Zone Configuration
Time Zone
Use this panel to select the time zone where the IN-tact 1101 is
located. This is necessary for the device to correctly calculate local
time based on the UTC time received from NTP server(s). Daylight
saving time is automatically calculated based on your time zone
choice. The default time zone is Arizona (GMT - 07:00).

NTP server(s) provided by DHCP
If DHCP is enabled and the IN-tact 1101 obtained NTP server
information from it, the first two NTP servers are displayed here and
are available for time synchronization.

Search NTP servers in this order
Use this panel to define the preferred search order for NTP servers.
Servers are contacted in the order you select. The default search
order is DHCP first, then statically-configured.

Time Synchronization Interval
Interval (hours)
Time is synchronized on start-up, then periodically according to the
interval configured you specify in this panel. The interval is specified
in hours, from 1 through 24, with 24 being the default. Time
synchronization can be requested whenever necessary by clicking
Synchronize Now. This button is only present if you have enabled
SNTP and restarted the device. A message displays to inform you
that the time synchronization process can take up to 40 seconds as a
valid NTP server is contacted. The result (failure or success) is
displayed on this page. An SNMP trap is generated when start-up
time synchronization fails. After that, a failed synchronization attempt
generates an event with no SNMP trap. If successful, the new time is
also displayed. A successful manual synchronization resets the
synchronization interval. In other words, the countdown until next
synchronization is reset to zero at the time you click Synchronize
Now. If you are using a SNMP manager to set time synchronization,
set your SNMP manager timeout to be at least 45 seconds to allow
adequate time for this operation to take place. Time will be
synchronized with the first server that successfully responds to the
request. An event is recorded stating that time has been successfully
synchronized, including the IP address of the NTP server that
responded to the time request.
