[Typo3] Date and time fields in the backend (in Extended Calendar)

[Justin Patrin]

The date fields in the backend while editing events for the Extended
Calendar are set up in a non-US way (I can deal with it but of course
my clients can't). I've changed the date and time formats in localconf
to what I want but those don't affect these BE fields. How can I alter
the formats to something different here?
