ITimeDeltaa Represent the difference between two datetime objects.
Implemented by `datetime.timedelta`.
Supported operators:
- add, subtract timedelta
- unary plus, minus, abs
- compare to timedelta
- multiply, divide by int/long
In addition, `.datetime` supports subtraction of two `.datetime` objects
returning a `.timedelta`, and addition or subtraction of a `.datetime`
and a `.timedelta` giving a `.datetime`.
Representation: (days, seconds, microseconds).

This may raise `ValueError`, if the timestamp is out of the range of
values supported by the platform C ``localtime()`` function. It's common
for this to be restricted to years from 1970 through 2038. Note that
on non-POSIX systems that include leap seconds in their notion of a
timestamp, leap seconds are ignored by `fromtimestamp`.

z&Between MINYEAR and MAXYEAR inclusive.zBetween 1 and 12 inclusivezFBetween 1 and the number of days in the given month of the given year.c C s dS )zReturn a date with the same value.
Except for those members given new values by whichever keyword
arguments are specified. For example, if ``d == date(2002, 12, 31)``, then
``d.replace(day=26) == date(2000, 12, 26)``.
Nr )yearmonthdayr r r replacez s z
IDate.replacec C s dS )a8 Return a 9-element tuple of the form returned by `time.localtime`.
The hours, minutes and seconds are 0, and the DST flag is -1.
``d.timetuple()`` is equivalent to
``(d.year, d.month, d.day, 0, 0, 0, d.weekday(), d.toordinal() -
date(d.year, 1, 1).toordinal() + 1, -1)``
Nr r r r r timetuple s zIDate.timetuplec C s dS )zReturn the proleptic Gregorian ordinal of the date
January 1 of year 1 has ordinal 1. For any date object *d*,
``date.fromordinal(d.toordinal()) == d``.
Nr r r r r toordinal s zIDate.toordinalc C s dS )zReturn the day of the week as an integer.
Monday is 0 and Sunday is 6. For example,
``date(2002, 12, 4).weekday() == 2``, a Wednesday.
.. seealso:: `isoweekday`.
Nr r r r r weekday s z
IDate.weekdayc C s dS )zReturn the day of the week as an integer.
Monday is 1 and Sunday is 7. For example,
date(2002, 12, 4).isoweekday() == 3, a Wednesday.
.. seealso:: `weekday`, `isocalendar`.
Nr r r r r
isoweekday s zIDate.isoweekdayc C s dS )am Return a 3-tuple, (ISO year, ISO week number, ISO weekday).
The ISO calendar is a widely used variant of the Gregorian calendar.
See http://www.phys.uu.nl/~vgent/calendar/isocalendar.htm for a good
explanation.
The ISO year consists of 52 or 53 full weeks, and where a week starts
on a Monday and ends on a Sunday. The first week of an ISO year is the
first (Gregorian) calendar week of a year containing a Thursday. This
is called week number 1, and the ISO year of that Thursday is the same
as its Gregorian year.
For example, 2004 begins on a Thursday, so the first week of ISO year
2004 begins on Monday, 29 Dec 2003 and ends on Sunday, 4 Jan 2004, so
that ``date(2003, 12, 29).isocalendar() == (2004, 1, 1)`` and
``date(2004, 1, 4).isocalendar() == (2004, 1, 7)``.
Nr r r r r isocalendar s zIDate.isocalendarc C s dS )zReturn a string representing the date in ISO 8601 format.
This is 'YYYY-MM-DD'.
For example, ``date(2002, 12, 4).isoformat() == '2002-12-04'``.
Nr r r r r isoformat s zIDate.isoformatc C s dS )z>For a date *d*, ``str(d)`` is equivalent to ``d.isoformat()``.Nr r r r r __str__ s z
IDate.__str__c C s dS )ap Return a string representing the date.
For example date(2002, 12, 4).ctime() == 'Wed Dec 4 00:00:00 2002'.
d.ctime() is equivalent to time.ctime(time.mktime(d.timetuple()))
on platforms where the native C ctime() function
(which `time.ctime` invokes, but which date.ctime() does not invoke)
conforms to the C standard.
Nr r r r r ctime s z IDate.ctimec C s dS )zReturn a string representing the date.
Controlled by an explicit format string. Format codes referring to
hours, minutes or seconds will see 0 values.

This is symbolic; this module does **not** make
`datetime.datetime` provide this interface.
z#The earliest representable datetimez!The latest representable datetimezCThe smallest possible difference between non-equal datetime objectsc C s dS )zReturn the current local datetime, with tzinfo None.
This is equivalent to ``datetime.fromtimestamp(time.time())``.
.. seealso:: `now`, `fromtimestamp`.
Nr r r r r r s zIDateTimeClass.todayNc C s dS )au Return the current local date and time.
If optional argument *tz* is None or not specified, this is like `today`,
but, if possible, supplies more precision than can be gotten from going
through a `time.time` timestamp (for example, this may be possible on
platforms supplying the C ``gettimeofday()`` function).
Else tz must be an instance of a class tzinfo subclass, and the current
date and time are converted to tz's time zone. In this case the result
is equivalent to tz.fromutc(datetime.utcnow().replace(tzinfo=tz)).
.. seealso:: `today`, `utcnow`.
Nr )tzr r r now s zIDateTimeClass.nowc C s dS )zReturn the current UTC date and time, with tzinfo None.
This is like `now`, but returns the current UTC date and time, as a
naive datetime object.
.. seealso:: `now`.
Nr r r r r utcnow s zIDateTimeClass.utcnowc C s dS )aU Return the local date and time corresponding to the POSIX timestamp.
Same as is returned by time.time(). If optional argument tz is None or
not specified, the timestamp is converted to the platform's local date
and time, and the returned datetime object is naive.
Else tz must be an instance of a class tzinfo subclass, and the
timestamp is converted to tz's time zone. In this case the result is
equivalent to
``tz.fromutc(datetime.utcfromtimestamp(timestamp).replace(tzinfo=tz))``.
fromtimestamp() may raise `ValueError`, if the timestamp is out of the
range of values supported by the platform C localtime() or gmtime()
functions. It's common for this to be restricted to years in 1970
through 2038. Note that on non-POSIX systems that include leap seconds
in their notion of a timestamp, leap seconds are ignored by
fromtimestamp(), and then it's possible to have two timestamps
differing by a second that yield identical datetime objects.
.. seealso:: `utcfromtimestamp`.
Nr )r r+ r r r r s z IDateTimeClass.fromtimestampc C s dS )aO Return the UTC datetime from the POSIX timestamp with tzinfo None.
This may raise `ValueError`, if the timestamp is out of the range of
values supported by the platform C ``gmtime()`` function. It's common for
this to be restricted to years in 1970 through 2038.
.. seealso:: `fromtimestamp`.
Nr )r r r r utcfromtimestamp s z IDateTimeClass.utcfromtimestampc C s dS )a$ Return the datetime from the proleptic Gregorian ordinal.
January 1 of year 1 has ordinal 1. `ValueError` is raised unless
1 <= ordinal <= datetime.max.toordinal().
The hour, minute, second and microsecond of the result are all 0, and
tzinfo is None.
Nr )r r r r r " s zIDateTimeClass.fromordinalc C s dS )a[ Return a new datetime object.
Its date members are equal to the given date object's, and whose time
and tzinfo members are equal to the given time object's. For any
datetime object *d*, ``d == datetime.combine(d.date(), d.timetz())``.
If date is a datetime object, its time and tzinfo members are ignored.

Nr r r r r timetzY s zIDateTime.timetzc C s dS )a, Return a datetime with the same members, except for those members
given new values by whichever keyword arguments are specified.
Note that ``tzinfo=None`` can be specified to create a naive datetime from
an aware datetime with no conversion of date and time members.
Nr )r r r hourminutesecond microsecondr r r r r ` s zIDateTime.replacec C s dS )a Return a datetime object with new tzinfo member tz, adjusting the
date and time members so the result is the same UTC time as self, but
in tz's local time.
tz must be an instance of a tzinfo subclass, and its utcoffset() and
dst() methods must not return None. self must be aware (self.tzinfo
must not be None, and self.utcoffset() must not return None).
If self.tzinfo is tz, self.astimezone(tz) is equal to self: no
adjustment of date or time members is performed. Else the result is
local time in time zone tz, representing the same UTC time as self:
after astz = dt.astimezone(tz), astz - astz.utcoffset()
will usually have the same date and time members as dt - dt.utcoffset().
The discussion of class `datetime.tzinfo` explains the cases at Daylight Saving
Time transition boundaries where this cannot be achieved (an issue only
if tz models both standard and daylight time).
If you merely want to attach a time zone object *tz* to a datetime *dt*
without adjustment of date and time members, use ``dt.replace(tzinfo=tz)``.
If you merely want to remove the time zone object from an aware
datetime dt without conversion of date and time members, use
``dt.replace(tzinfo=None)``.
Note that the default `tzinfo.fromutc` method can be overridden in a
tzinfo subclass to effect the result returned by `astimezone`.

YYYY-MM-DDTHH:MM:SS.mmmmmm or YYYY-MM-DDTHH:MM:SS if microsecond is 0
If `utcoffset` does not return None, a 6-character string is appended,
giving the UTC offset in (signed) hours and minutes:
YYYY-MM-DDTHH:MM:SS.mmmmmm+HH:MM or YYYY-MM-DDTHH:MM:SS+HH:MM
if microsecond is 0.
The optional argument sep (default 'T') is a one-character separator,
placed between the date and time portions of the result.
