This module defines a method to parse an ISO 8601:2004 date time string.
For this job it uses the parse_date and parse_time methods defined in date
and time module.

Parses ISO 8601 date-times into datetime.datetime objects.
This function uses parse_date and parse_time to do the job, so it allows
more combinations of date and time representations, than the actual
ISO 8601:2004 standard allows.

Format datetime strings.
This method is just a wrapper around isodate.isostrf.strftime and uses
Extended-Complete as default format.
