prompt the correct date/time format in the error message

prompt the correct date/time format in the error message in case the user want to manually input the date/time fields.

The strings are the same as in db/models/fields/init.py

This seems like a logical change. Giving people more information about errors is generally better.

I don't know about the "programmery" strings like: HH:MM[:ss[.uuuuuu]]. I dunno if people need to know about microseconds. Perhaps just using HH:MM there?

[dryice]

The strings are the same as in source:django/trunk/django/db/models/fields/__init__.py to be consistent. But yes, I agree that end user don't need to know about microseconds most of the time.

I'm not sure this is a good idea. It relies on the assumption that the field needs to be entered in a specific format. What if you're using a SelectDateWidget, or alternative input_formats on the field?

"the assumption that the field needs to be entered in a specific format" is not coded in this patch, it's already in the code for DateField/TimeField/DateTimeField

However I saw another reason why the patch should not be applied: Because the format check in the existing code has been i18n-ed, and checking all the formats.py in django/conf/locale/xx, there's no a universal format. So specifying the YYYY-MM-DD format in the error message may confuse some users don't use this format.
