Date and Time tab
Use this menu to set the date and time on the UTM Firewall appliance. Setting the appliance clock to the
correct date and time is important; otherwise, the timestamps of system log messages do not match the
time of the event. If you use certificates for SSL or IPSec, it is especially important that you set the date
and time correctly, as certificates include a start date and time before which they do not function and an
expiry date and time after which they do not function. All changes to the time are logged in the System Log
to assist with tracking a chain of events.
When the time and date is set through the Management Console, or retrieved from an NTP server, the
hardware clock of the UTM Firewall appliance is automatically updated. The hardware clock uses a battery
to allow the current time and date to be maintained across reboots, and after the appliance has been
powered down for longer periods of time.
Setting locality
Setting a locale (time zone) is only relevant if you are synchronizing with an NTP server or your UTM
Firewall appliance has a real time clock (all but the SG300 have a real time clock). After you select your
local region, the system clock shows local time. Without setting locale, the system clock shows UTC
(Coordinated Universal Time) time.
Prerequisite: You must set your Locality before you set the date and time.
