Field
Daylight Savings
Time
Description
This parameter controls whether to set the displayed time to
the daylight savings time. If it is set to Yes and the optional
rule is empty, then the displayed time will be 1 hour ahead of
the normal time.
The daylight savings time will be automatically adjusted
according to the rule set in the Optional Rule field. The rule
syntax include: start-time end-time and saving. Both
start-time and end-time have the same syntax: month, day,
weekday, hour, minute.
Month: 1,2,3, ... , 12 (for Jan, Feb, .., Dec)
Day: [+|-]1,2,3, ... , 31
Weekday: 1, 2, 3, ... , 7 (for Mon, Tue, .., Sun), or 0 that
means the daylight saving rule is not based on weekdays
but based on the day of the month.
hour: hour (0– 23)
minute: minute (0– 59)
If weekday is set to 0, it means the daylight saving time starts
or ends at the given date. In this case, the day value cannot be
negative. If weekday is not set to 0 and the day value is
positive, then the daylight saving time starts on the first " day"
iteration of the weekday (such as 1st Sunday, 3rd Tuesday
etc).
If weekday is not set to 0 and the day value is negative, then
the daylight saving time starts on the last " day"iteration of
the weekday (last Sunday, 3rd last Tuesday etc).This feature
is supported on the phone only when you have correctly set
the NTP server.).
The saving takes " minute"as the unit. The saving time may
also be preceded by a negative (– ) sign if subtraction is
desired instead of addition.
When the default Automatic Daylight Saving Time Rule
value is set to 3,2,7,2,0;11,1,7,2,0;60, which complies the
rule of US.
For example:
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 2 am and ends on the first Sunday of
November at 2 am. The saving is 60 minutes.
