Example
The following is an example of a proper POSIX string:
START and END Indicates when to change to and return from the
daylight saving time. The
START argument is the date
when the change from the standard to the daylight
save time occurs;
END is the date for changing back.
If
START and END are not specified, the default is the
US Daylight saving time start and end dates. The
format for start and end must be one of the following:
• n where
n is the number of days since the
start of the year from 1 to 365. It must
contain the leap year day if the current year
is a leap year. With this format, it is your
responsibility to determine all the leap year
details.
• Jn where
n is the number of days since the
start of the year from 1 to 365. Leap days
are not counted. The
TIME parameter has
the same format as
OFFSET but there can
be no leading minus (-) or plus (+) sign. If
TIME is not specified, the default is
02:00:00 .
• Mx[x].y.z where
x is the month, y is a week
count and
z is the day of the week starting
at 0 (Sunday). As an example,
M10.5.0 is
the Sunday of the fifth week of October.
The
TIME parameter has the same format
as
OFFSET but there can be no leading
minus (-) or plus (+) sign. If TIME is not
specified, the default is
02:00:00 .
