Daylight Saving Rules

Last Updated : Jan 09, 2013 |

Administers up to 15 customized daylight saving rules. Specifies the exact date and time each daylight saving rule goes into effect and when it stops. Rule 0 makes no adjustment to the system clock for daylight saving and cannot be modified.

In this example, Rule 1 applies to all time zones in the U.S. and begins on the first Sunday on or after March 8 at 2:00 a.m. with a 01:00 increment. Daylight Saving Time stops on the first Sunday on or after November 1 at 2:00 a.m., also with a 01:00 increment used as a decrement when switching back to Standard time. Telephone displays reflect these settings.

1:	Start: first _ Sunday_ on or after _March   8_ at 2:00_  01:00__
	Stop:  first _ Sunday_ on or after November 1_ at 2:00_
