Time Zone
You can set the time settings for the Router on this screen.
Figure 99
Time Zone Screen
The Router keeps time by connecting to a Network Time Protocol (NTP)
server. This allows the Router to synchronize the system clock to the
Internet. The synchronized clock in the Router is used to record the
security log and control client filtering. Select the time zone that you
reside in.
If you reside in an area that observes Daylight Saving, then check the
E
nable
Daylight Savings box. The system clock may not update
immediately. Allow at least 15 minutes for the Router to contact the time
servers on the Internet and get a response. You cannot set the clock
yourself.
You can specify which NTP servers the Router will use to update the
system clock, although doing this should only be necessary if you are
experiencing difficulty.
