Objets 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-check macros:

int PyDate_Check(PyObject *ob)

   Return true if *ob* is of type "PyDateTime_DateType" or a subtype
   of "PyDateTime_DateType".  *ob* must not be *NULL*.

int PyDate_CheckExact(PyObject *ob)

   Return true if *ob* is of type "PyDateTime_DateType". *ob* must not
   be *NULL*.

   of "PyDateTime_TimeType".  *ob* must not be *NULL*.

Macros to create objects:

PyObject* PyDate_FromDate(int year, int month, int day)
    *Return value: New reference.*

   Return a "datetime.date" object with the specified year, month and
   day.

   Nouveau dans la version 2.4.

PyObject* PyDateTime_FromDateAndTime(int year, int month, int day, int hour, int minute, int second, int usecond)
    *Return value: New reference.*

   Return a "datetime.datetime" object with the specified year, month,
   day, hour, minute, second and microsecond.

   Nouveau dans la version 2.4.

PyObject* PyTime_FromTime(int hour, int minute, int second, int usecond)
    *Return value: New reference.*

   Return a "datetime.time" object with the specified hour, minute,
   second and microsecond.

   Nouveau dans la version 2.4.

PyObject* PyDelta_FromDSU(int days, int seconds, int useconds)
    *Return value: New reference.*

   Return a "datetime.timedelta" object representing the given number
   of days, seconds and microseconds.  Normalization is performed so
   that the resulting number of microseconds and seconds lie in the
   ranges documented for "datetime.timedelta" objects.

Macros to extract fields from date objects.  The argument must be an
instance of "PyDateTime_Date", including subclasses (such as
"PyDateTime_DateTime").  The argument must not be *NULL*, and the type
is not checked:

int PyDateTime_GET_YEAR(PyDateTime_Date *o)

   Return the year, as a positive int.

   Nouveau dans la version 2.4.

int PyDateTime_GET_MONTH(PyDateTime_Date *o)

   Return the month, as an int from 1 through 12.

   Nouveau dans la version 2.4.

int PyDateTime_GET_DAY(PyDateTime_Date *o)

   Return the day, as an int from 1 through 31.

   Nouveau dans la version 2.4.

Macros to extract fields from datetime objects.  The argument must be
an instance of "PyDateTime_DateTime", including subclasses. The
argument must not be *NULL*, and the type is not checked:

   Return the hour, as an int from 0 through 23.

   Nouveau dans la version 2.4.

int PyDateTime_DATE_GET_MINUTE(PyDateTime_DateTime *o)

   Return the minute, as an int from 0 through 59.
