In my time zone (Australia), date question types require dates to be input in day/month/year format, e.g. 15/05/2014.
When I download Questionnaire responses in text format, dates are also in day/month/year format.
However, when email confirmations are generated by Questionnaire, dates are formatted in year-month-day format, e.g. 2014-05-15.
I suspect it's due to the Time API. See: http://docs.moodle.org/dev/Time_API
Is it possible somehow to make the date format in email confirmations consistent with Questionnaire date question type?
