Locality
Select your region then select your location within said region. The system clock will
subsequently show local time. Without setting this, the system clock will show UTP.
Setting a time zone is only relevant if you are synchronizing with an NTP server or your
CyberGuard SG appliance has a real time clock. Without either of these, the
CyberGuard SG appliance's clock is set randomly at startup.
