From you have I been [A] absent in the spring,
When proud-pied April dress'd in all his trim
Hath put [A’] a spirit of youth in every thing
That heavy Saturn laugh'd and leap'd [B] with him.
Yet nor the lays of birds nor the sweet smell
Of different flowers in odor and in hue
Could make me any summer's story tell.
Or from their proud lap pluck them while they grew;
Nor did I wonder at the lily's white,
Nor praise the deep vermilion in the rose;
They were but sweet, but figures of delight;
Drawn after you, you pattern of all those.
Yet seem'd it winter still, and, you away,
As with your shadow I with these did play.
(Virginia Woolf, To the Lighthouse, p.132; Sonnet 98, William Shakespeare)
The present perfect ([A] and [A’]) seems not refer to the past Reference Time [B]. I guess the present perfects are selected to say the gloomy away from you has lasted till now. Is this right?
