[Pharo-project] Does anyone have tried/succeeded to use PetitParser for parsing dates?

I wonder if anyone has used PetitParser to parse dates in diverse formats. e.g 01/01/2012 07/31/2012 And with failures on things like 2012-07-32 or 2012-13-01 or 2012-02-30 or 2011-02-29 Regards Friedrich -- Q-Software Solutions GmbH; Sitz: Bruchsal; Registergericht: Mannheim Registriernummer: HRB232138; Geschaeftsfuehrer: Friedrich Dominicus
