Wondering whether my validates_timeliness plugin may give some ideas on the date/time parsing front. The Formats class handles I18n parsing http://github.com/adzap/validates_timeliness/blob/572d80d227f4e727350c3adc82e174cdf55a0de2/lib/validates_timeliness/formats.rb
It also includes a suboptimal solution for the date ambiguities you mentioned. Suboptimal because its either one or the other interpretation for the whole app, which is not ideal. I plan to refactor the class to allow format filtering on the fly and also date disambiguation based on the locale.
