DateTime 对象P
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。
宏访问UTC单例:
-
PyObject*
PyDateTime_TimeZone_UTC
P 返回表示 UTC 的时区单例,与
datetime.timezone.utc
为同一对象。3.7 新版功能.
类型检查宏:
-
int

PyDateTime_DateType
类型或PyDateTime_DateType
的某个子类型则返回真值。 ob 不能为NULL
。
-
int

PyDateTime_DateTimeType
类型或PyDateTime_DateTimeType
的某个子类型则返回真值。 ob 不能为NULL
。
-
int
PyTime_Check
(PyObject *ob)P 如果 ob 的类型是
PyDateTime_TimeType
或是PyDateTime_TimeType
的子类型则返回真值。 ob 必须不为NULL
。
-
int
PyDelta_Check
(PyObject *ob)P 如果 ob 为
PyDateTime_DeltaType
类型或PyDateTime_DeltaType
的某个子类型则返回真值。 ob 不能为NULL
。
-
int
PyTZInfo_Check
(PyObject *ob)P 如果 ob 为
PyDateTime_TZInfoType
类型或PyDateTime_TZInfoType
的某个子类型则返回真值。 ob 不能为NULL
