For a main-sequence star, yes. For a neutron star, at ~12 -- 30 km diameter, light-speed timescales are on the order of 40--100 microseconds, which would be the lower bound on whole-star cataclysmic events. (Time dilation might extend this somewhat, perhaps by a factor of two or so.) For a white dwarf, ~10,000 km, lightspeed events would be about 30 milliseconds (~300 times longer than on the neutron star). That's about 1/10 of an eyeblink.
