5.3.3.1 Time Zone
The router does not have a real time clock on board; instead, it uses the Simple Network Time
Protocol (SNTP) to get the current time from an SNTP server outside your network. Choose your
local time zone, click
Enable and click the Apply button. After a successful connection to the
Internet, the router retrieves the correct local time from the SNTP server you have specified. If
you prefer to specify an SNTP server other than those in the drop-down list, simply enter its IP
address as shown above. Your ISP may provide an SNTP server for you to use.
Resync Period (in minutes) is the periodic interval the router waits before it resynchronizes the
router’s time with that of the specified SNTP server. To avoid unnecessarily increasing the load on
your specified SNTP server you should keep the poll interval as high as possible – at the absolute
minimum every few hours or even days.
