FieldtypeDatetime translation breaks saving field

[BernhardBaumrock]

Short description of the issue

I'm working on a Datetime related module and think I found a bug!

My user's language is german, I set the field input to this:

When showing an already populated field, it looks fine:

But when I change the time to this:

Which means "PM" in english and I save the page:

---> Data lost!

Expected behavior

Translations should not break the field functionality.

Actual behavior

All times without translated strings like "PM --> NACHM." work.

Actually @jmartsch shouldn't "AM" also be translated to "VORM." ?
