Setting the Time and Time Zone
The PL9950-BBR Router keeps time by connecting to a Simple Network Time Protocol (SNTP)
server. This allows the PL9950-BBR Router to synchronize the system clock to the global internet.
The synchronized clock in the PL9950-BBR Router is used to record the security log and control
client filtering. Select the time zone you reside in. If you reside in an area that observes daylight
saving, then place a check mark in the box next to
Enable Daylight Saving
. The system clock
may not update immediately. Allow at least 15 minutes for the PL9950-BBR Router to contact the
time servers on the Internet and receive a response. You cannot set the clock yourself.

System Logs
The PL9950-BBR Router maintains a System Log which displays potential security threats and
system information. This log can be viewed with a browser using the gateway’s web
management interface, or it can be automatically sent to an email address for convenience
and archiving. Each log entry contains the date and time of the event and a brief message
describing the event. It is possible to copy the log entries from the web management interface
and paste into a report.
The System Log displays the following message types:
