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 :c:macro:`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, :c:data:`PyDateTimeAPI`, that is used by the following
|
|
macros.
|
|
|
|
Type-check macros:
|
|
|
|
.. c:function:: int PyDate_Check(PyObject *ob)
|
|
|
|
Return true if *ob* is of type :c:data:`PyDateTime_DateType` or a subtype of
|
|
:c:data:`PyDateTime_DateType`. *ob* must not be *NULL*.
|
|
|
|
|
|
.. c:function:: int PyDate_CheckExact(PyObject *ob)
|
|
|
|
Return true if *ob* is of type :c:data:`PyDateTime_DateType`. *ob* must not be
|
|
*NULL*.
|
|
|
|
|
|
.. c:function:: int PyDateTime_Check(PyObject *ob)
|
|
|
|
Return true if *ob* is of type :c:data:`PyDateTime_DateTimeType` or a subtype of
|
|
:c:data:`PyDateTime_DateTimeType`. *ob* must not be *NULL*.
|
|
|
|
|
|
.. c:function:: int PyDateTime_CheckExact(PyObject *ob)
|
|
|
|
Return true if *ob* is of type :c:data:`PyDateTime_DateTimeType`. *ob* must not
|
|
be *NULL*.
|
|
|
|
|
|
.. c:function:: int PyTime_Check(PyObject *ob)
|
|
|
|

|
|
:c:data:`PyDateTime_TimeType`. *ob* must not be *NULL*.
|
|
|
|
|
|
.. c:function:: int PyTime_CheckExact(PyObject *ob)
|
|
|
|

|
*NULL*.
|
|
|
|
|
|
.. c:function:: int PyDelta_Check(PyObject *ob)
|
|
|
|
Return true if *ob* is of type :c:data:`PyDateTime_DeltaType` or a subtype of
|
|
:c:data:`PyDateTime_DeltaType`. *ob* must not be *NULL*.
|
|
|
|
|
|
.. c:function:: int PyDelta_CheckExact(PyObject *ob)
|
|
|
|

|
|
*NULL*.

|
|
|
|
Return true if *ob* is of type :c:data:`PyDateTime_TZInfoType` or a subtype of
|
|
:c:data:`PyDateTime_TZInfoType`. *ob* must not be *NULL*.
|
|
|
|
|
|
.. c:function:: int PyTZInfo_CheckExact(PyObject *ob)
|
|
|
|
Return true if *ob* is of type :c:data:`PyDateTime_TZInfoType`. *ob* must not be

|
|
number of microseconds and seconds lie in the ranges documented for
|
|
``datetime.timedelta`` objects.
