DateTime Objects — Python documentation
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, 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.
Type-check macros:
- int PyDate_Check(PyObject *ob)
- Return true if ob is of type
PyDateTime_DateType
or a subtype ofPyDateTime_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 ofPyDateTime_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 ofPyDateTime_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 ofPyDateTime_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 ofPyDateTime_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 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 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 a
datetime.time
object with the specified hour, minute, second and microsecond.
- PyObject *PyDelta_FromDSU(int days, int seconds, int useconds)
- 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 fordatetime.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 to extract fields from time delta objects. The argument must be an instance of PyDateTime_Delta
, including subclasses. The argument must not be NULL, and the type is not checked:
- int PyDateTime_DELTA_GET_DAYS(PyDateTime_Delta *o)
Return the number of days, as an int from -999999999 to 999999999.
New in version 3.3.
- int PyDateTime_DELTA_GET_SECONDS(PyDateTime_Delta *o)
Return the number of seconds, as an int from 0 through 86399.
New in version 3.3.
- int PyDateTime_DELTA_GET_MICROSECONDS(PyDateTime_Delta *o)
Return the number of microseconds, as an int from 0 through 999999.
New in version 3.3.
Macros for the convenience of modules implementing the DB API:
- Create and return a new
datetime.datetime
object given an argument tuple suitable for passing todatetime.datetime.fromtimestamp()
.
- Create and return a new
datetime.date
object given an argument tuple suitable for passing todatetime.date.fromtimestamp()
.
