-This module provides an alternative strftime method.
-
-The strftime method in this module allows only a subset of Python's strftime
-format codes, plus a few additional. It supports the full range of date values
-possible with standard Python date/time objects. Furthermore there are several
-pr-defined format strings in this module to make ease producing of ISO 8601
-conforming strings.
