7.5.12 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 include by Python.h), and macro PyDateTime_IMPORT()
must be invoked. The macro arranges to put a pointer to a C structure
in a static variable PyDateTimeAPI, which 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.
New in version 2.4.
| int PyDate_CheckExact( | PyObject *ob) |
-
Return true if ob is of type PyDateTime_DateType.
ob must not be NULL.
New in version 2.4.
| 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.
New in version 2.4.
| int PyDateTime_CheckExact( | PyObject *ob) |
-
Return true if ob is of type PyDateTime_DateTimeType.
ob must not be NULL.
New in version 2.4.
| 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.
New in version 2.4.
| int PyTime_CheckExact( | PyObject *ob) |
-
Return true if ob is of type PyDateTime_TimeType.
ob must not be NULL.
New in version 2.4.
| 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.
New in version 2.4.
| int PyDelta_CheckExact( | PyObject *ob) |
-
Return true if ob is of type PyDateTime_DeltaType.
ob must not be NULL.
New in version 2.4.
| 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.
New in version 2.4.
| int PyTZInfo_CheckExact( | PyObject *ob) |
-
Return true if ob is of type PyDateTime_TZInfoType.
ob must not be NULL.
New in version 2.4.
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.
New in version 2.4.
| 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.
New in version 2.4.
| 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.
New in version 2.4.
| 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.
New in version 2.4.
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.
New in version 2.4.
| int PyDateTime_GET_MONTH( | PyDateTime_Date *o) |
-
Return the month, as an int from 1 through 12.
New in version 2.4.
| int PyDateTime_GET_DAY( | PyDateTime_Date *o) |
-
Return the day, as an int from 1 through 31.
New in version 2.4.
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.
New in version 2.4.
| int PyDateTime_DATE_GET_MINUTE( | PyDateTime_DateTime *o) |
-
Return the minute, as an int from 0 through 59.
New in version 2.4.
| int PyDateTime_DATE_GET_SECOND( | PyDateTime_DateTime *o) |
-
Return the second, as an int from 0 through 59.
New in version 2.4.
| int PyDateTime_DATE_GET_MICROSECOND( | PyDateTime_DateTime *o) |
-
Return the microsecond, as an int from 0 through 999999.
New in version 2.4.
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.
New in version 2.4.
| int PyDateTime_TIME_GET_MINUTE( | PyDateTime_Time *o) |
-
