GR translation: feel your age delivered into a new kind of time

[Mike Jing]

V471.33-472.3, P479.27-39   . . . she looked at him once, of course he
still remembers, from down at the end of a lunchwagon counter, grill
smoke working onto the windows patient as shoe grease against the rain
for the plaid, hunched-up leaky handful inside, off the jukebox a
quick twinkle in the bleat of a trombone, a reed section, planting
swing notes precisely into the groove between silent midpoint and next
beat, jumping it pah (hm) pah (hm) pah so exactly in the groove that
you knew it was ahead but felt it was behind, both of you, at both
ends of the counter, could feel it, feel your age delivered into a new
kind of time that may have allowed you to miss the rest, the graceless
expectations of old men who watched, in bifocal and mucus
indifference, watched you lindy-hop into the pit by millions, as many
millions as necessary. . . .

Here the word 'time" is used in the sense related to music, is that correct?
