Time Zone
You can set the time settings for the Router on this screen.
Figure 104
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
Enable 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.

Traceroute
Traceroute is the program that shows you the route over the network
between two systems, listing all the intermediate routers a connection
must pass through to get to its destination. It can help you determine
why your connections to a given server might be poor, and can often help
you figure out where exactly the problem is. It also shows you how
systems are connected to each other, letting you see how your ISP
connects to the Internet as well as how the target system is connected.
