GR translation: gathering in their minutes whining

[Mike Jing]

V133.34-40, P136.7-12   In the night, the deepest concrete wells of night,
dynamos whose locations are classified spin faster, and so, responding, the
clock-hands next to all the old, sleepless eyes—gathering in their minutes
whining, pitching higher toward the vertigo of a siren. It is the Night’s
Mad Carnival. There is merriment under the shadows of the minute-hands.
Hysteria in the pale faces between the numerals.

What is "minutes whining" exactly?
