Used to convert different time specifications to a common format. The time object can be relative (i.e. indicate a time increment, or a time of day) or absolute. Objects from the :class:`datetime` module that are timezone-naive will be assumed to be in UTC, if ``bot`` is not passed or ``bot.defaults`` is :obj:`None`. Args: time_object (:obj:`float` | :obj:`datetime.timedelta` | :obj:`datetime.datetime` | :obj:`datetime.time`): Time value to convert. The semantics of this parameter will depend on its type: * :obj:`float` will be interpreted as "seconds from :paramref:`reference_t`" * :obj:`datetime.timedelta` will be interpreted as "time increment from :paramref:`reference_timestamp`" * :obj:`datetime.datetime` will be interpreted as an absolute date/time value * :obj:`datetime.time` will be interpreted as a specific time of day reference_timestamp (:obj:`float`, optional): POSIX timestamp that indicates the absolute time from which relative calculations are to be performed (e.g. when :paramref:`time_object` is given as an :obj:`int`, indicating "seconds from :paramref:`reference_time`"). Defaults to now (the time at which this function is called). If :paramref:`time_object` is given as an absolute representation of date & time (i.e. a :obj:`datetime.datetime` object), :paramref:`reference_timestamp` is not relevant and so its value should be :obj:`None`. If this is not the case, a :exc:`ValueError` will be raised. tzinfo (:class:`datetime.tzinfo`, optional): If :paramref:`time_object` is a naive object from the :mod:`datetime` module, it will be interpreted as this timezone. Defaults to ``pytz.utc``, if available, and :attr:`datetime.timezone.utc` otherwise. Note: Only to be used by ``telegram.ext``. Returns: :obj:`float` | :obj:`None`: The return value depends on the type of argument :paramref:`time_object`. If :paramref:`time_object` is given as a time increment (i.e. as a :obj:`int`, :obj:`float` or :obj:`datetime.timedelta`), then the return value will be :paramref:`reference_timestamp` + :paramref:`time_object`. Else if it is given as an absolute date/time value (i.e. a :obj:`datetime.datetime` object), the equivalent value as a POSIX timestamp will be returned. Finally, if it is a time of the day without date (i.e. a :obj:`datetime.time` object), the return value is the nearest future occurrence of that time of day. Raises: TypeError: If :paramref:`time_object` s type is not one of those described above. ValueError: If :paramref:`time_object` is a :obj:`datetime.datetime` and :paramref:`reference_timestamp` is not :obj:`None`.
