have been painting和having worked 分别是什么时态?

have been painting 完成进行时,表示动作已经开始,但没有结束,并有可能持续下去。having worked having worked本身并不是单一的时态。应该是做补语,本应该是have worked。完成时比如:After having worked so many year,he suddenly felt tired。这里having worked只是补语。如果这样,He is having worked so many years。这句话是错的。所以说having worked本身并不是单一的时态,单have worked才是完成时
