System > Time

The System > Time page defines the time and date settings to time stamp log events, to automatically update SonicWALL Security Services, and for other internal purposes.

By default, the SonicWALL security appliance uses an internal list of public NTP servers to automatically update the time. Network Time Protocol (NTP) is a protocol used to synchronize computer clock times in a network of computers. NTP uses Coordinated Universal Time (UTC) to synchronize computer clock times to a millisecond, and sometimes to a fraction of a millisecond.

System Time

To select automatically update the time, choose the time zone from the Time Zone menu. Set time automatically using NTP is activated by default to use NTP (Network Time Protocol) servers from an internal list to set time automatically. Automatically adjust clock for daylight saving time is also activated by default to enable automatic adjustments for daylight savings time.

If you want to set your time manually, uncheck Set time automatically using NTP . Select the time in the 24-hour format using the Time (hh:mm:ss) menus and the date from the Date menus.

Selecting Display UTC in logs (instead of local time) specifies the use universal time (UTC) rather than local time for log events.

Selecting Display date in International format displays the date in International format, with the day preceding the month.

Selecting Only use custom NTP servers directs SonicOS to use the manually entered list of NTP servers to set the SonicWALL security appliance clock, rather than using the internal list of NTP servers.

After selecting your System Time settings, click Accept .

NTP Settings

Network Time Protocol (NTP) is a protocol used to synchronize computer clock times in a network of computers. NTP uses Coordinated Universal Time (UTC) to synchronize computer clock times to a millisecond, and sometimes, to a fraction of a millisecond.

Tip

The SonicWALL security appliance uses an internal list of NTP servers so manually entering a NTP server is optional.

Select Use NTP to set time automatically if you want to use your local server to set the SonicWALL security appliance clock. You can also configure Update Interval (minutes) for the NTP server to update the SonicWALL security appliance. The default value is 60 minutes.

To add an NTP server to the SonicWALL security appliance configuration

Step 1

Click Add . The Add NTP Server window is displayed.

Step 2

Type the IP address of an NTP server in the NTP Server field.

Step 3

Click OK .

Step 4

Click Accept on the System > Time page to update the SonicWALL security appliance.

To delete an NTP server, highlight the IP address and click Delete . Or, click Delete All to delete all servers.
