True when timepoint is within the duration of component in seconds:

abjad> contexttools.TempoMark(Duration(1, 2), 60, target_context = Staff)(staff)
TempoMark(Duration(1, 2), 60)(Staff{4})
abjad> leaf = staff.leaves[0]
abjad> componenttools.number_is_between_start_and_stop_offsets_of_component_in_seconds(0.1, leaf)
True
abjad> componenttools.number_is_between_start_and_stop_offsets_of_component_in_seconds(0.333, leaf) # doctest: +SKIP
True
Otherwise false:
abjad> componenttools.number_is_between_start_and_stop_offsets_of_component_in_seconds(0.5, staff) # doctest: +SKIP
