US EST
When we change our clocks

Beginning in 2007, most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time.


time_zone: EST ; Time Zone Phone is in
dst_offset: 1 ; Offset from Phone's time when DST is in effect
dst_start_month: Mar ; Month in which DST starts
dst_start_day: "" ; Day of month in which DST starts
dst_start_day_of_week: Sun ; Day of week in which DST starts
dst_start_week_of_month: 2 ; Week of month in which DST starts
dst_start_time: 02 ; Time of day in which DST starts
dst_stop_month: Nov ; Month in which DST stops
dst_stop_day: "" ; Day of month in which DST stops
dst_stop_day_of_week: Sunday ; Day of week in which DST stops
dst_stop_week_of_month: 1 ; Week of month in which DST stops 8=last week of month
dst_stop_time: 2 ; Time of day in which DST stops
dst_auto_adjust: 1 ; Enable(1-Default)/Disable(0) DST automatic adjustment
time_format_24hr: 1 ; Enable(1 - 24Hr Default)/Disable(0 - 12Hr)

The next example in bold is has the old dates for US DST

7940/60 Daylight Savings configuration

dst_offset: 1	Offset from Phone's time when DST is in effect
dst_start_month: April	Month in which DST starts
dst_start_day: ""	Day of month in which DST starts
dst_start_day_of_week: Sun	Day of week in which DST starts
dst_start_week_of_month: 1	Week of month in which DST starts
dst_start_time: 02	Time of day in which DST starts
dst_stop_month: Oct	Month in which DST stops
dst_stop_day: ""	Day of month in which DST stops
dst_stop_day_of_week: Sunday	Day of week in which DST stops
dst_stop_week_of_month: 8	Week of month in which DST stops 8=last week of month
dst_stop_time: 2	Time of day in which DST stops
dst_auto_adjust: 1	Enable(1-Default)/Disable(0) DST automatic adjustment
time_format_24hr: 1	Enable(1 - 24Hr Default)/Disable(0 - 12Hr)

Depending on the way your locale sets its policy for the start and end of DST it appears Cisco will allow you to set a combination of one or more of the start/end day/day_of_week/week_of_month options. For example if DST is set to start in the 1st week of november you would set dst_start_month=november and dst_start_week_of_month=1

DST Times

TAS	1/10/2006	25/3/2007
