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.
