[Typo3-dev] Modify Date Format in TCA

[Keith Morrison]

Hi all,

OK, I've RTFM, scoured google, etc, and I can't find an answer to this 
question: how do I change the format of a date field in the backend? 
Since I'm in the U.S., my users won't stop complaining about the date 
being dd-mm-yy, and I want to change it so that it reads mm-dd-yy.  So, 
if they click on the checkbox, it will pop up the current date+1 in the 
field in that format; also, the solution would ideally stop screwing up 
the Date2Calendar extension--somewhere, some code is restricting the mm 
part of dd-mm-yy to go no higher than 12, which is probably some 
error-checking javascript to keep months in the correct range.  I'd 
appreciate anyone just pointing out the right file(s) to me at this point.

Thanks,
Keith

PS If you are feeling especially generous, you might give me some advice 
on how to deal with users who are also complaining about the 24-hour 
clock, instead of using AM/PM--anyone have any experience here?
