+There is a third approach to setting up date time values, which leverages
+the 'task calc' command. You can simply set any datetime attribute to
+any string that contains an acceptable TaskWarrior-formatted time expression::
+
+    $ task calc now + 1d
+    2015-07-17T21:17:54
+
+This syntax can be leveraged in the python interpreter as follows::
+
+    >>> t['due'] = "now + 1d"

+    datetime.datetime(2015, 7, 17, 21, 19, 31, tzinfo=<DstTzInfo 'Europe/Berlin' CEST+2:00:00 DST>)

+It can be easily seen that the string with TaskWarrior-formatted time expression
+is automatically converted to native datetime in the local time zone.

+For the list of acceptable formats and keywords, please consult:

 By default, TaskWarrior uses configuration values stored in your .taskrc.

-    >>> tw.config
+    >>> tw.overrides

 To pass your own configuration overrides, you just need to update this dictionary::
 
-    >>> tw.config.update({'hooks': 'off'})  # tasklib will not trigger hooks
+    >>> tw.overrides.update({'hooks': 'off'})  # tasklib will not trigger hooks
