	Table 10 Basic Setting > General Setup (continued)
	LABEL	DESCRIPTION
	Use Time	Enter the time service protocol that your timeserver uses. Not all time
	Server when	servers support all protocols, so you may have to use trial and error to
	Bootup	find a protocol that works. The main differences between them are the
		time format.
		When you select the Daytime (RFC 867) format, the Switch displays
		the day, month, year and time with no time zone adjustment. When you
		use this format it is recommended that you use a Daytime timeserver
		within your geographical time zone.
		Time (RFC-868)format displays a 4-byte integer giving the total
		number of seconds since 1970/1/1 at 0:0:0.
		NTP (RFC-1305)is similar to Time (RFC-868).
		None is the default value. Enter the time manually. Each time you turn
		on the Switch, the time and date will be reset to 1970-1-1 0:0.

	Time Sync	Enter the time interval time and the switch will sync with timeserver.
	Interval

	Time Server IP	Enter the IP address of your timeserver. The Switch searches for the
	Address	timeserver for up to 60 seconds. If you select a timeserver that is
		unreachable, then this screen will appear locked for 60 seconds. Please
		wait.

	Current Time	This field displays the time you open this menu (or refresh the menu).

	New Time	Enter the new time in hour, minute and second format. The new time
	(hh:min:ss)	then appears in the Current Time field after you click Apply.

	Current Date	This field displays the date you open this menu.

	New Date	Enter the new date in year, month and day format. The new date then
	(yyyy-mm-dd)	appears in the Current Date field after you click Apply.

	Time Zone	Select the time difference between UTC (Universal Time Coordinated,
		formerly known as GMT, Greenwich Mean Time) and your time zone from
		the drop-down list box.

	Daylight	Daylight saving is a period from late spring to early fall when many
	Saving Time	countries set their clocks ahead of normal local time by one hour to give
		more daytime light in the evening.
		Select this option if you use Daylight Saving Time.

	Start Date	Configure the day and time when Daylight Saving Time starts if you
		selected Daylight Saving Time. The time is displayed in the 24 hour
		format. Here are a couple of examples:
		Daylight Saving Time starts in most parts of the United States on the
		second Sunday of March. Each time zone in the United States starts
		using Daylight Saving Time at 2 A.M. local time. So in the United States
		you would select Second, Sunday, March and 2:00.
		Daylight Saving Time starts in the European Union on the last Sunday of
		March. All of the time zones in the European Union start using Daylight
		Saving Time at the same moment (1 A.M. GMT or UTC). So in the
		European Union you would select Last, Sunday, March and the last
		field depends on your time zone. In Germany for instance, you would
		select 2:00 because Germany's time zone is one hour ahead of GMT or
		UTC (GMT+1).
