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. The macro puts a pointer to a C structure into a static variable, PyDateTimeAPI, that is used by the following macros.

Type-check macros:

int PyDate_Check(PyObject *ob)

Return true if ob is of type PyDateTime_DateType or a subtype of PyDateTime_DateType. ob must not be NULL.

int PyDate_CheckExact(PyObject *ob)

Return true if ob is of type PyDateTime_DateType. ob must not be NULL.

int PyDateTime_Check(PyObject *ob)

Return true if ob is of type PyDateTime_DateTimeType or a subtype of PyDateTime_DateTimeType. ob must not be NULL.

int PyDateTime_CheckExact(PyObject *ob)

Return true if ob is of type PyDateTime_DateTimeType. ob must not be NULL.

int PyTime_Check(PyObject *ob)

Return true if ob is of type PyDateTime_TimeType or a subtype of PyDateTime_TimeType. ob must not be NULL.

int PyTime_CheckExact(PyObject *ob)

Return true if ob is of type PyDateTime_TimeType. ob must not be NULL.

int PyDelta_Check(PyObject *ob)

Return true if ob is of type PyDateTime_DeltaType or a subtype of PyDateTime_DeltaType. ob must not be NULL.

int PyDelta_CheckExact(PyObject *ob)

Return true if ob is of type PyDateTime_DeltaType. ob must not be NULL.

int PyTZInfo_Check(PyObject *ob)

Return true if ob is of type PyDateTime_TZInfoType or a subtype of PyDateTime_TZInfoType. ob must not be NULL.

int PyTZInfo_CheckExact(PyObject *ob)

Return true if ob is of type PyDateTime_TZInfoType. ob must not be NULL.

Macros to create objects:

PyObject* PyDate_FromDate(int year, int month, int day)

Return value: New reference.

Return a datetime.date object with the specified year, month and day.

PyObject* PyDateTime_FromDateAndTime(int year, int month, int day, int hour, int minute, int second, int usecond)

Return value: New reference.

Return a datetime.datetime object with the specified year, month, day, hour, minute, second and microsecond.

PyObject* PyTime_FromTime(int hour, int minute, int second, int usecond)

Return value: New reference.

Return a datetime.time object with the specified hour, minute, second and microsecond.

PyObject* PyDelta_FromDSU(int days, int seconds, int useconds)

Return value: New reference.

Return a datetime.timedelta object representing the given number of days, seconds and microseconds. Normalization is performed so that the resulting number of microseconds and seconds lie in the ranges documented for datetime.timedelta objects.

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_YEAR(PyDateTime_Date *o)

Return the year, as a positive int.

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:

int PyDateTime_DATE_GET_HOUR(PyDateTime_DateTime *o)

Return the hour, as an int from 0 through 23.

int 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.

Macros to extract fields from time objects. The argument must be an instance of PyDateTime_Time, including subclasses. The argument must not be NULL, and the type is not checked:

int PyDateTime_TIME_GET_HOUR(PyDateTime_Time *o)

Return the hour, as an int from 0 through 23.

int PyDateTime_TIME_GET_MINUTE(PyDateTime_Time *o)

Return the minute, as an int from 0 through 59.

int PyDateTime_TIME_GET_SECOND(PyDateTime_Time *o)

Return the second, as an int from 0 through 59.

int PyDateTime_TIME_GET_MICROSECOND(PyDateTime_Time *o)

Return the microsecond, as an int from 0 through 999999.

Macros for the convenience of modules implementing the DB API:

PyObject* PyDateTime_FromTimestamp(PyObject *args)

Return value: New reference.

Create and return a new datetime.datetime object given an argument tuple suitable for passing to datetime.datetime.fromtimestamp().

PyObject* PyDate_FromTimestamp(PyObject *args)

Return value: New reference.

Create and return a new datetime.date object given an argument tuple suitable for passing to datetime.date.fromtimestamp().
