Various date and time objects are supplied by the :mod:`datetime` module.
9
Before using any of these functions, the header file :file:`datetime.h` must be
10
included in your source (note that this is not included by :file:`Python.h`),
11
and the macro :cfunc:`PyDateTime_IMPORT` must be invoked. The macro puts a
12
pointer to a C structure into a static variable, ``PyDateTimeAPI``, that is
13
used by the following macros.
17
.. cfunction:: int PyDate_Check(PyObject *ob)
19
Return true if *ob* is of type :cdata:`PyDateTime_DateType` or a subtype of
20
:cdata:`PyDateTime_DateType`. *ob* must not be *NULL*.
23
.. cfunction:: int PyDate_CheckExact(PyObject *ob)
25
Return true if *ob* is of type :cdata:`PyDateTime_DateType`. *ob* must not be
29
.. cfunction:: int PyDateTime_Check(PyObject *ob)
31
Return true if *ob* is of type :cdata:`PyDateTime_DateTimeType` or a subtype of
32
:cdata:`PyDateTime_DateTimeType`. *ob* must not be *NULL*.
35
.. cfunction:: int PyDateTime_CheckExact(PyObject *ob)

.. cfunction:: int PyTime_Check(PyObject *ob)
43
Return true if *ob* is of type :cdata:`PyDateTime_TimeType` or a subtype of

:cdata:`PyDateTime_TimeType`. *ob* must not be *NULL*.
47
.. cfunction:: int PyTime_CheckExact(PyObject *ob)
49
Return true if *ob* is of type :cdata:`PyDateTime_TimeType`. *ob* must not be
53
.. cfunction:: int PyDelta_Check(PyObject *ob)
55
Return true if *ob* is of type :cdata:`PyDateTime_DeltaType` or a subtype of
56
:cdata:`PyDateTime_DeltaType`. *ob* must not be *NULL*.
59
.. cfunction:: int PyDelta_CheckExact(PyObject *ob)
61
Return true if *ob* is of type :cdata:`PyDateTime_DeltaType`. *ob* must not be
65
.. cfunction:: int PyTZInfo_Check(PyObject *ob)
67
Return true if *ob* is of type :cdata:`PyDateTime_TZInfoType` or a subtype of
68
:cdata:`PyDateTime_TZInfoType`. *ob* must not be *NULL*.
71
.. cfunction:: int PyTZInfo_CheckExact(PyObject *ob)
73
Return true if *ob* is of type :cdata:`PyDateTime_TZInfoType`. *ob* must not be
77
Macros to create objects:
79
.. cfunction:: PyObject* PyDate_FromDate(int year, int month, int day)
81
Return a ``datetime.date`` object with the specified year, month and day.
84
.. cfunction:: PyObject* PyDateTime_FromDateAndTime(int year, int month, int day, int hour, int minute, int second, int usecond)
86
Return a ``datetime.datetime`` object with the specified year, month, day, hour,
87
minute, second and microsecond.
90
.. cfunction:: PyObject* PyTime_FromTime(int hour, int minute, int second, int usecond)
92
Return a ``datetime.time`` object with the specified hour, minute, second and
96
.. cfunction:: PyObject* PyDelta_FromDSU(int days, int seconds, int useconds)
98
Return a ``datetime.timedelta`` object representing the given number of days,
99
seconds and microseconds. Normalization is performed so that the resulting
100
number of microseconds and seconds lie in the ranges documented for
101
``datetime.timedelta`` objects.
104
Macros to extract fields from date objects. The argument must be an instance of
105
:cdata:`PyDateTime_Date`, including subclasses (such as
106
:cdata:`PyDateTime_DateTime`). The argument must not be *NULL*, and the type is
109
.. cfunction:: int PyDateTime_GET_YEAR(PyDateTime_Date *o)
111
Return the year, as a positive int.
114
.. cfunction:: int PyDateTime_GET_MONTH(PyDateTime_Date *o)
116
Return the month, as an int from 1 through 12.
119
.. cfunction:: int PyDateTime_GET_DAY(PyDateTime_Date *o)
121
Return the day, as an int from 1 through 31.
124
Macros to extract fields from datetime objects. The argument must be an
125
instance of :cdata:`PyDateTime_DateTime`, including subclasses. The argument
126
must not be *NULL*, and the type is not checked:
128
.. cfunction:: int PyDateTime_DATE_GET_HOUR(PyDateTime_DateTime *o)
130
Return the hour, as an int from 0 through 23.
133
.. cfunction:: int PyDateTime_DATE_GET_MINUTE(PyDateTime_DateTime *o)
135

138
.. cfunction:: int PyDateTime_DATE_GET_SECOND(PyDateTime_DateTime *o)
140
Return the second, as an int from 0 through 59.
143
.. cfunction:: int PyDateTime_DATE_GET_MICROSECOND(PyDateTime_DateTime *o)
145
Return the microsecond, as an int from 0 through 999999.
148
Macros to extract fields from time objects. The argument must be an instance of
149
:cdata:`PyDateTime_Time`, including subclasses. The argument must not be *NULL*,
150
and the type is not checked:
152
.. cfunction:: int PyDateTime_TIME_GET_HOUR(PyDateTime_Time *o)
154
