Having a controllable global base model allows us to customize all the models within the app. For instance, we can enforce a standard datetime format or introduce a common method for all subclasses of the base model.

from typing import Any
from zoneinfo import ZoneInfo

from fastapi.encoders import jsonable_encoder
from pydantic import BaseModel, ConfigDict, field_serializer
