# DateTime Objects

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.

PyDateTime_IMPORT()

  Import the datetime C API.

  On success, populate the `PyDateTimeAPI` pointer. On failure, set `PyDateTimeAPI` to `NULL` and set an exception. The caller must check if an error occurred via `PyErr_Occurred()`:

      PyDateTime_IMPORT;
      if (PyErr_Occurred()) { /* cleanup */ }

  Ostrzeżenie

  This is not compatible with subinterpreters.

  Zmienione w wersji 3.15: This macro is now thread safe.

type PyDateTime_CAPI

  Structure containing the fields for the datetime C API.

  The fields of this structure are private and subject to change.

  Do not use this directly; prefer `PyDateTime_*` APIs instead.

PyDateTime_CAPI *PyDateTimeAPI

  Dynamically allocated object containing the datetime C API.

  This variable is only available once `PyDateTime_IMPORT` succeeds.

  Zmienione w wersji 3.15: This variable should not be accessed directly as direct access is not thread-safe. Use `PyDateTime_IMPORT()` instead.

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 the 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.

Macro for access to the UTC singleton:

PyObject *PyDateTime_TimeZone_UTC

  Returns the time zone singleton representing UTC, the same object as `datetime.timezone.utc`.

  Dodane w wersji 3.7.
