For example, the default DST rule is
start=4/1/7;end=10/-1/7;save=1.
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
month
value equals any value in the range 1-12 (January-December).
The
day
value equals any + or - 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.
Optional time values:
HH
represents hours (0-23),
mm
represents minutes (0-59).
and
ss
represents seconds (0-59). Optional values inside brackets [ ] are assumed
to be 0 if not specified. Midnight is represented by 0:0:0 of the given date.
The
save-time
value is the number of hours, minutes, and/or seconds to add to the
current time during DST. The
save-time
value can be preceded by a plus (+) or
minus (-) sign to indicate addition or subtraction.
Daylight Saving Time Examples
The following example configures daylight savings time for the U.S, adding one
hour starting at midnight on the first Sunday in April and ending at midnight on the
last Sunday of October; add 1 hour (USA, North America):
start=4/1/7/0:0:0;end=10/31/7/0:0:0;save=1
start=4/1/7;end=10/-1/7;save=1
start=4/1/7/0;end=10/-1/7/0;save=1
The following example configures daylight savings time for Egypt, starting at
midnight on the last Sunday in April and ending at midnight on the last Sunday of
September:
start=4/-1/7;end=9/-1/7;save=1 (Egypt)
