Objek DateTime¶
Various date and time objects are supplied by the datetime
module.
Before using any of these functions, the header file datetime.h
must be
included in your source (note that this is not included by Python.h
),
and the 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, PyDateTimeAPI
, that is used by the following
macros.
-
type PyDateTime_Delta¶
This subtype of
PyObject
represents the difference between two datetime values.
-
PyTypeObject PyDateTime_DateType¶
This instance of
PyTypeObject
represents the Python date type; it is the same object asdatetime.date
in the Python layer.
-
PyTypeObject PyDateTime_DateTimeType¶
This instance of
PyTypeObject
represents the Python datetime type; it is the same object asdatetime.datetime
in the Python layer.
-
PyTypeObject PyDateTime_TimeType¶
This instance of
PyTypeObject
represents the Python time type; it is the same object asdatetime.time
in the Python layer.
-
PyTypeObject PyDateTime_DeltaType¶
This instance of
PyTypeObject
represents Python type for the difference between two datetime values; it is the same object asdatetime.timedelta
in the Python layer.
-
PyTypeObject PyDateTime_TZInfoType¶
This instance of
PyTypeObject
represents the Python time zone info type; it is the same object asdatetime.tzinfo
in the Python layer.
