Description
Enter the rule for calculating daylight saving time.
This rule is comprised of three fields. Each field is
separated by a semicolon (;). Optional values inside
brackets [ ] are assumed to be 0 if they are not
specified. Midnight is represented by colons. For
example, 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).
Default: 3/-1/7/2;end=10/-1/7/2;save=1.
