# Objetos 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_Date

  This subtype of `PyObject` represents a Python date object.

type PyDateTime_DateTime

  This subtype of `PyObject` represents a Python datetime object.

type PyDateTime_Time

  This subtype of `PyObject` represents a Python time object.

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 as `datetime.date` in the Python layer.

PyTypeObject PyDateTime_DateTimeType

  This instance of `PyTypeObject` represents the Python datetime type; it is the same object as `datetime.datetime` in the Python layer.

PyTypeObject PyDateTime_TimeType

  This instance of `PyTypeObject` represents the Python time type; it is the same object as `datetime.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 as `datetime.timedelta` in the Python layer.

PyTypeObject PyDateTime_TZInfoType

  This instance of `PyTypeObject` represents the Python time zone info type; it is the same object as `datetime.tzinfo` in the Python layer.
