+PostgreSQL can store data as INTERVAL type, which is close to meaning the
+same as python's timedelta object (although better in a couple of ways).
+I have lots of use for timedelta objects, and having code that basically
+wrapped integer objects as a number of seconds was common. This module
+ * a timedelta.TimedeltaField() object that transparently converts
+ to and from datetime.timedelta
+ * storage of the data as an INTERVAL in PostgreSQL, or a string in
+ other databases. (Other databases will be considered if I ever
+ use them, or receive patches).
+The coolest part of this package is the way it manipulates strings entered
+by users, and presents them. Any string of the format:
+ [X weeks,] [Y days,] [Z hours,] [A minutes,] [B seconds]
+will be converted to a timedelta object. Even shortened versions can be used:
+hrs, hr or h will also suffice. The parsing ignores trailing 's', but is
+smart about adding them in when presenting the data to the user.
+To use, install the package, and use the field::
+ from django.db import models
+ class MyModel(models.Model):
+ the_timedelta = timedelta.TimedeltaField()
+There are also some useful methods in helpers.py to work with timedelta
+objects. (eg, multiply, divide, modulo and percentages).
+Handle strings with times in other languages. I'm not really sure about how
+to do this, but it may be useful.
+0.4.4: Restore functionality for django <1.2 (thanks Yoav Aner).
+0.4.3: Added helpers.modulo, to allow remainder division of timedlelta objects.
+0.4.1: changed get_db_prep_value() code to be in get_prep_value(), since I
+ was calling it in get_default(), without a connection value.
+0.4: added the connection and prepared arguments to get_db_prep_value(),
+ so that django 1.3+ will not complain of DeprecationWarnings.
