Daylight Saving Time Rule
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.
• The abbreviation HH stands for hours (0-23).
• The abbreviation mm stands for minutes (0-59).
• The abbreviation ss stands for seconds (0-59).
The default Daylight Saving Time Rule is start=4/1/7;end=10/-1/7;save=1.
