DateTime Objects
----------------
Various date and time objects are supplied by the :mod:`datetime` module.
Before using any of these functions, the header file :file:`datetime.h` must be
included in your source (note that this is not included by :file:`Python.h`),
and the macro :cmacro:`PyDateTime_IMPORT` must be invoked, usually as part of
the module initialisation function. The macro puts a pointer to a C structure
into a static variable, :cdata:`PyDateTimeAPI`, that is used by the following
macros.
Type-check macros:
.. cfunction:: int PyDate_Check(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_DateType` or a subtype of
:cdata:`PyDateTime_DateType`. *ob* must not be *NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyDate_CheckExact(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_DateType`. *ob* must not be
*NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_Check(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_DateTimeType` or a subtype of
:cdata:`PyDateTime_DateTimeType`. *ob* must not be *NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_CheckExact(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_DateTimeType`. *ob* must not
be *NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyTime_Check(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_TimeType` or a subtype of
:cdata:`PyDateTime_TimeType`. *ob* must not be *NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyTime_CheckExact(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_TimeType`. *ob* must not be
*NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyDelta_Check(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_DeltaType` or a subtype of
:cdata:`PyDateTime_DeltaType`. *ob* must not be *NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyDelta_CheckExact(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_DeltaType`. *ob* must not be
*NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyTZInfo_Check(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_TZInfoType` or a subtype of
:cdata:`PyDateTime_TZInfoType`. *ob* must not be *NULL*.
.. versionadded:: 2.4
.. cfunction:: int PyTZInfo_CheckExact(PyObject *ob)
Return true if *ob* is of type :cdata:`PyDateTime_TZInfoType`. *ob* must not be
*NULL*.
.. versionadded:: 2.4
Macros to create objects:
.. cfunction:: PyObject* PyDate_FromDate(int year, int month, int day)
Return a ``datetime.date`` object with the specified year, month and day.
.. versionadded:: 2.4
.. cfunction:: PyObject* PyDateTime_FromDateAndTime(int year, int month, int day, int hour, int minute, int second, int usecond)
Return a ``datetime.datetime`` object with the specified year, month, day, hour,
minute, second and microsecond.
.. versionadded:: 2.4
.. cfunction:: PyObject* PyTime_FromTime(int hour, int minute, int second, int usecond)
Return a ``datetime.time`` object with the specified hour, minute, second and
microsecond.
.. versionadded:: 2.4
.. cfunction:: PyObject* PyDelta_FromDSU(int days, int seconds, int useconds)
Return a ``datetime.timedelta`` object representing the given number of days,
seconds and microseconds. Normalization is performed so that the resulting
number of microseconds and seconds lie in the ranges documented for
``datetime.timedelta`` objects.
.. versionadded:: 2.4
Macros to extract fields from date objects. The argument must be an instance of
:cdata:`PyDateTime_Date`, including subclasses (such as
:cdata:`PyDateTime_DateTime`). The argument must not be *NULL*, and the type is
not checked:
.. cfunction:: int PyDateTime_GET_YEAR(PyDateTime_Date *o)
Return the year, as a positive int.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_GET_MONTH(PyDateTime_Date *o)
Return the month, as an int from 1 through 12.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_GET_DAY(PyDateTime_Date *o)
Return the day, as an int from 1 through 31.
.. versionadded:: 2.4
Macros to extract fields from datetime objects. The argument must be an
instance of :cdata:`PyDateTime_DateTime`, including subclasses. The argument
must not be *NULL*, and the type is not checked:
.. cfunction:: int PyDateTime_DATE_GET_HOUR(PyDateTime_DateTime *o)
Return the hour, as an int from 0 through 23.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_DATE_GET_MINUTE(PyDateTime_DateTime *o)
Return the minute, as an int from 0 through 59.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_DATE_GET_SECOND(PyDateTime_DateTime *o)
Return the second, as an int from 0 through 59.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_DATE_GET_MICROSECOND(PyDateTime_DateTime *o)
Return the microsecond, as an int from 0 through 999999.
.. versionadded:: 2.4
Macros to extract fields from time objects. The argument must be an instance of
:cdata:`PyDateTime_Time`, including subclasses. The argument must not be *NULL*,
and the type is not checked:
.. cfunction:: int PyDateTime_TIME_GET_HOUR(PyDateTime_Time *o)
Return the hour, as an int from 0 through 23.
.. versionadded:: 2.4
.. cfunction:: int PyDateTime_TIME_GET_MINUTE(PyDateTime_Time *o)

suitable for passing to ``datetime.date.fromtimestamp()``.
