From what we see with GER's power, it is triggered by a direct attack against Giorno. SInce Pucci's ability is indiscriminate (and causes no physical effect on Giorno), it seems Giorno would not be able to revert the time acceleration. However, since both abilities are based around fate, Giorno would likely remain unaffected after the universe resets.
