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.
