[BUG] Serializing datetime.time loses timezone data when datetime.datetime is reqired for utc offset because of DST

[07pepa]

Since i encountered this issue while re-implementing your serialization of time for beanie in python (BeanieODM/beanie#912)

there is issue when zone info can't get you precise utc offset without some date time (because of DST)

i know folowimg code this is pydantic... but what causes error is in here

pydantic-core/src/input/datetime.rs

Line 177 in e1fc99d

pub fn pytime_as_time(py_time: &Bound<'_, PyAny>, py_dt: Option<&Bound<'_, PyAny>>) -> PyResult<Time> {

and here

pydantic-core/src/input/datetime.rs

Line 207 in e1fc99d

Self::Py(py_time) => pytime_as_time(py_time, None),

    from pydantic import BaseModel
    from datetime import time
    from zoneinfo import ZoneInfo
    class TimeTest(BaseModel):
        t: time


    assert (TimeTest(t=time(12, 4, 5, 123456, tzinfo=ZoneInfo("America/Fortaleza")))
            .model_dump(mode="json")) != (TimeTest(t=time(12, 4, 5, 123456, tzinfo=ZoneInfo("Europe/Prague")))
                                          .model_dump(mode="json")) #fails

you can see it causes loss of data and is and there is way how to safely cover 99% of timezones (see my python implementation)
