Chapter 9: Configuring Time Settings
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 your time zone and 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 changes is also activated by default to enable automatic
adjustments for daylight savings time.
