Stale version of TIME_INPUT_FORMATS used by dojango.form.fields.TimeField

[GoogleCodeExporter]

Reason:
Dojango overwrites dj_settings.TIME_INPUT_FORMATS, but doesn't clear cache 
"_format_cache" of django.utils.formats.get_format().

Details:
If get_format(TIME_INPUT_FORMATS) is called before D-o-jango overwrites 
dj_settings.TIME_INPUT_FORMATS, "_format_cache" is filled with Django default 
value, and this value is returned for every subsequent call of 
get_format(TIME_INPUT_FORMATS), no matter what actual settings value will be at 
calling time.

What version of the product are you using? On what operating system?

Django trunk, Dojango 0.5.1 final

Could you provide a fix for that issue?

Django docs suggest that "You shouldn't alter settings in your applications at 
runtime.". If we accept this rule, Dojango README should encourage users to add 
Dojango's TIME_INPUT_FORMATS manually.
Otherwise, the only solution I see is to clear 
django.utils.formats._format_*cache, after modifying the settings at runtime.

I'm voting for the first option.

Should be fixed in r286.
