DateTime 对象¶
datetime 模块提供了各种日期和时间对象。 在使用任何这些函数之前,必须在你的源码中包含头文件 datetime.h (请注意此文件并未包含在 Python.h 中),并且宏 PyDateTime_IMPORT 必须被发起调用,通常是作为模块初始化函数的一部分。 这个宏会将指向特定 C 结构的指针放入一个静态变量 PyDateTimeAPI 中,它会由下面的宏来使用。

datetime.timezoneobject with a fixed offset represented by the offset argument and with tzname name.3.7 新版功能.
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_MONTH(PyDateTime_Date *o)¶ Return the month, as an int from 1 through 12.
-
int
PyDateTime_GET_DAY(PyDateTime_Date *o)¶ Return the day, as an int from 1 through 31.
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:

PyDateTime_DATE_GET_MINUTE(PyDateTime_DateTime *o)¶ Return the minute, as an int from 0 through 59.
-
int
PyDateTime_DATE_GET_SECOND(PyDateTime_DateTime *o)¶ Return the second, as an int from 0 through 59.
-
int
PyDateTime_DATE_GET_MICROSECOND(PyDateTime_DateTime *o)¶ Return the microsecond, as an int from 0 through 999999.
