Unable to stop incorrect date exports

Question

How do we set up a form in Adobe Acrobat XI that allows dates to be formatted a certain way (mmm/dd/yyyy) and exported in the same way to Excel and always be recognized as a "proper" date in Excel?
Currently the following does not work (Attempt #1):
Set up a field; Set the format category as date; Set up a Custom format of "mmm/dd/yyyy"
Create a distribution file
When users fill out the form if they type in an incorrect date, eg., "August 27 2013", the form automagically shows the date on the PDF as "Aug/27/13" - Great!
When the users submit the form and it's brought into the response file the dates are shown in a default date format of mm/dd/yyyy - Fine, once the form owners understand this
When the form owners export the information the data exported is the same as the original users entered it, not as it was automagically formatted to. For instance, if submitters originally entered "August 27, 2013" then that's what goes across to Excel. And some of these formats Excel doesn't know how to convert. - Understandably frustrating for form owners
Attempt #2: As a workaround we set up special formatting that has a mask of "AAA/99/9999". This at least provides forces the users to use the same formatting, but is confusing the submitters when they need to enter dates from 1-9 and we've also found that the conversion of this format to a date in Excel doesn't work, but at least it's consistent! Javascript was also added to force users to use specific month abbreviations.
d = new Date(event.value.replace(/-/g, " "));
if (!Date.parse(d)){app.alert("Please enter in a proper date.\n\nThe month abbreviations are: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec");}
Attempt #3: The last attempt was to continue to use the set up as Attempt #1, but to also use the javascript from Attempt #2. The theory being that if a user entered in "August 27 2013" the javascript would complain. Alas, the javascript appears to run after Adobe automagically does its date format conversion.
Does anyone know how to get around this or have any other ideas to either enforce a usable date format or have Adobe export the dates as they've been automatically formatted to? We've tried to find a way to turn off the automatic date conversion that Adobe's running, but haven't found a way yet. Another option seemed to be to allow a masking that allowed for optional characters (so that the "0" wouldn't be needed for the dates 1-9) but there doesn't seem to be one.
Thanks in advance!

Answer 1

Since there was no clear way to ensure that the date formatting was correct prior to exporting, we're going to get the respondants to use drop downs to ensure the formatting is correct. Not the most convenient for the users though as they're accustomed to being able to type in the values to select it (e.g., for the date of 23 they would expect to enter 2 then 3 for 23) based on other applications, but the Adobe pull downs don't "group" what's been entered (e.g., 2 then 3 will select 30, not 23) and so it will take them a bit to get used to it. I still can't believe that Adobe wouldn't simply export what it's been formatted to though... after all that's what we set the form up for.
