Table 64. Time Zone screen settings
Setting Description
Date/Time From the drop-down list, select the local time zone in which the VPN firewall
operates. The correct time zone is required in order for scheduling to work
correctly. The VPN firewall includes a real-time clock (RTC), which it uses for
scheduling.
Automatically Adjust for
Daylight Savings Time
If daylight savings time is supported in your region, select the Automatically
Adjust for Daylight Savings Time check box.
Select NTP Mode In all three NTP modes, the VPN firewall functions both as a client and a server.
The VPN firewall synchronizes its clock with the specified NTP server or servers
and provides time service to clients. From the drop-down list, select the NTP
mode:
• Authoritative Mode. The VPN firewall synchronizes its clock with the
specified NTP server or servers on the Internet. If external servers are
unreachable, the VPN firewall’s RTC provides time service to clients. In
authoritative mode, you can enter a stratum value and set the date and time
manually.
• Sync to NTP Servers on Internet. The VPN firewall synchronizes its clock
with the specified NTP server or servers on the Internet. If external servers are
unreachable, the VPN firewall does not use its RTC.
• Sync to NTP Servers on VPN. The VPN firewall synchronizes its clock with
the specified NTP server on the VPN. If the server is unreachable, the VPN
firewall does not use its RTC. You need to select a VPN policy that enables the
VPN firewall to contact the NTP server on the VPN.
Select Stratum In authoritative mode, enter a stratum value, which
indicates the distance from a reference clock. The default
value is 10, which specifies an unsynchronized local clock
and causes NTP to use the VPN firewall’s RTC when the
specified NTP server is not available.
Set date and time
manually
This is an optional setting that is available in authoritative
mode. Select the check box to unmask the time (hour,
minute, second), Day, Month, and Year fields. Enter the
date and time.
Select VPN Policy When the VPN firewall is configured to synchronize to an
NTP server on the VPN, select the VPN policy from the
drop-down list. For information about configuring VPN
policies, see Configure VPN Policies on page 167.
