So that the log entries are properly time-stamped and sent at the correct time, be sure to set the

time as described in the next section.

Setting the Time

from one of several network time servers on the Internet. To localize the time for your log entries,

you must specify your time zone:

•

Time Zone

. Select your local time zone. This setting is used for the blocking schedule and for

time-stamping log entries.

•

Automatically Adjust for Daylight Savings Time

. Select this check box if your region

supports daylight savings time. The router will automatically adjust the time at the start and

end of the daylight savings time period.
