Setting :paramref:`first` to ``0``, ``datetime.datetime.now()`` or another

to how the APScheduler library works. If you want to run a job immediately,

depending on its type. See :paramref:`first` for details.
If :paramref:`last` is :obj:`datetime.datetime` or :obj:`datetime.time` type
and ``last.tzinfo`` is :obj:`None`, the default timezone of the bot will be
assumed, which is UTC unless :attr:`telegram.ext.Defaults.tzinfo` is used.
