	This option applies to GXP-1200/GXP-2000 only.

	This parameter controls time displayed in daylight savings time. If set to “Yes”, then the
Daylight Savings Time
	displayed time will be 1 hour ahead of normal time.

The “Optional Rule” is configured to automatically adjust the Daylight Savings Time (DST) based on the rule set in this field.

Rule Syntax:

•start-time; end-time; saving

•Both start-time and end-time have the same syntax: month,day,weekday,hour,minute o month: 1,2,3,..,12 (for Jan, Feb, .., Dec)

o day: [+-]1,2,3,..,31

o weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 which means the daylight saving rule is not based on week days but based on the day of the month.

o hour: hour (0-23), minute: minute (0-59)

If “weekday” is 0, it means the date to start or end daylight saving is at exactly the given date. In that case, the “day” value must not be negative. If “weekday” is not zero and “day” is positive, then the daylight saving starts on the first “day” the iteration of the weekday (e.g.: 1st Sunday, 3rd Tuesday etc). If “weekday” is not zero and “day” is negative, then the daylight saving starts on the last “day” the iteration of the weekday (e.g.: last Sunday, 3rd last Tuesday etc).

	The saving is in the unit of minutes. The saving time may also be preceded by a negative (-)
	sign if subtraction is desired instead of addition.
	The default value is set for US, the “Automatic Daylight Saving Time Rule” shall be set to
	“3,2,7,2,0;11,1,7,2,0;60”
	Examples
	US/Canada where daylight saving time is applicable:
	03,02,7,02,00;11,1,7,02,00;60
	This means the daylight saving time starts from the second Sunday of March at 2AM and
	ends the first Sunday of November at 2AM. The saving is 60 minutes.
