DateTime 物件¶
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.
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
