Description
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).
The <weekday> value equals any value in the range 1-7
(Monday-Sunday). It can also equal 0. If the <weekday> value
is 0, this means that the date to start or end daylight saving is
exactly the date given. In that case, the <day> value must not
be negative. If the <weekday> value is not 0 and the <day>
value is positive, then daylight saving starts or ends on the
<weekday> value on or after the date given. If the <weekday>
value is not 0 and the <day> value is negative, then daylight
saving starts or ends on the <weekday> value on or before the
date given. Where:
HH stands for hours (0-23).
mm stands for minutes (0-59).
ss stands for seconds (0-59).
The default Daylight Saving Time Rule is
start=3/-1/7/2;end=10/-1/7/2;save=1.
Select Yes to enable Daylight Saving Time.
