The speed of the flare up would entirely depend upon the size of the star compared to the forces around it, and how far it into space it flared up. If the distance that the expansion occured was only a short one and the power behind the initial implosion and consequent explosion were very high, plus the environmental forces in the region (including gravity) did not restrict the expansion phase, then certainly short duration supernova's are possible and probably very common.
