Jumping Ahead

I manage to get some reading time in these days and have begun to notice a trend that even some of my favorite, well-known authors are doing, and that is skipping ahead with regard to the time frame. I've done it myself, sometimes at the end of a story I'll do a brief chapter starting out, one year later kind of thing. But a few of the books I've read lately go over the top in my opinion.

Recently I read an author who I love. Through most of the book the writing went smoothly and at a nice pace. However, the last few chapters had me frowning as she would start some chapters and even paragraphs with something like three weeks later , then six months later , then four days later , and on it went until finally the end. It left me with the feeling that she got tired of writing the story and just wanted to get it over with, instead of writing out what her characters were doing.

For some reason that bugs the crap out of me, so I wanted to get your ideas on it. Does it bother you when an author jumps ahead like that in her story line? Just curious.
