30232	Correct expected format in invalid DurationField error message	Aidas Bendoraitis	Adrian Vassallo	"If you enter a duration ""14:00"" into a duration field, it translates to ""00:14:00"" which is 14 minutes.

The current error message for invalid DurationField says that this should be the format of durations: ""[DD] [HH:[MM:]]ss[.uuuuuu]"". But according to the actual behaviour, it should be: ""[DD] [[HH:]MM:]ss[.uuuuuu]"", because seconds are mandatory, minutes are optional, and hours are optional if minutes are provided.

This seems to be a mistake in all Django versions that support the DurationField.

Also the duration fields could have a default help_text with the requested format, because the syntax is not self-explanatory."	Bug	closed	Database layer (models, ORM)	2.2	Normal	fixed			Ready for checkin	1	0	0	0	1	1
