28090	TimeField's value incorrectly localized in forms	Tomek Rej	nobody	"When passing a `datetime.time` instance to the choices parameter in a `TimeField`, the admin template converts it to a human readable form. For example, `time(0, 0)` is converted to ""midnight"", `time(1, 30)` is converted to 1:30 a.m. In Django 1.10, it gets formatted as 00:00:00 and 01:30:00 respectively.

An example of the choices I pass in to the constructor is:

{{{
[
    (datetime.time(0, 0), '00:00'),
    (datetime.time(0, 30), '00:30'),
    (datetime.time(1, 0), '01:00'),
    ....,
    (datetime.time(23, 30), '23:30')
]
}}}

This causes the admin form validation to fail with errors like the following:
''Select a valid choice. midnight is not one of the available choices.''"	Bug	closed	Forms	1.11	Normal	duplicate		ygan@…	Accepted	0	0	0	0	0	0
