"Some", and an ever decreasing number, since relatively few still exist,
whether or not they get hurt by turning counterclockwise.
My watch and three clocks, plus my computer, changed time by themselves,
since they get time information over the radio.
One kitchen wall clock was analog. The rest (and there are lots) were
digital, they don't go backwards for reasons of design simplicity, but
wouldn't be hurt if they could be turned back, and unplugging them would
get a blank display, nt an hour later time.
