Rule
Description
When used with some routers that have DHCP with
time offset values configured, the IP phone uses the
router settings and ignores the IP phone time zone and
offset settings. To ignore the router DHCP time offset
value, and use the local time zone and offset settings,
choose yes for this option. Choosing no causes the IP
phone to use the router's DHCP time offset value. The
default value is yes.
NOTE Found in the Time section for the Cisco SPA525G or
Cisco SPA525G2.
Enter the rule for calculating daylight saving time; it
should include the start, end, and save values. This rule
is comprised of three fields. Each field is separated by
; (a semicolon) as shown below. Optional values inside
[ ] (the brackets) are assumed to be 0 if they are not
specified. Midnight is represented by 0:0:0 of the given
date.
This is the format of the rule: Start = <start-time>;
end=<end-time>; save = <save-time>.
The <start-time> and <end-time> values specify the
start and end dates and times of daylight saving time.
Each value is in this format: <month> /<day> /
<weekday>[/HH:[mm[:ss]]]
The <save-time> value is the number of hours, minutes,
and/or seconds to add to the current time during
daylight saving time. The <save-time> value can be
preceded by a negative (-) sign if subtraction is
desired instead of addition. The <save-time> value is in
this format: [/[+|-]HH:[mm[:ss]]]
The <month> value equals any value in the range 1-12
(January-December).
The <day> value equals [+|-] any value in the range 1-
31.
If <day> is 1, it means the <weekday> on or before the
end of the month (in other words the last occurrence of
< weekday> in that month).
