New in version 1.1.
Get component start offset in seconds:
abjad> staff = Staff("c'8 d'8 e'8 f'8")
abjad> score = Score([staff])
abjad> contexttools.TempoMark(Duration(1, 4), 52)(score)
TempoMark(Duration(1, 4), 52)(Score<<1>>)
abjad> f(score) # doctest: +SKIP
\new Score <<
\new Staff {
\tempo 4=52
c'8
d'8
e'8
f'8
}
>>
abjad> componenttools.get_component_start_offset_in_seconds(score.leaves[1])
Offset(15, 26)
Return nonnegative fraction.
