I kind of think it is rocket science, since so many people have tried to write their own variant of it. We don't really do that for version control, IDEs, compilers, email clients, browsers, or the myriad other tools software developers use daily. Sure, some of us do, but most of us don't. But I think we've all taken a stab at time-tracking and task-tracking, even if that just means we're writing things on post-it notes or in a journal. I don't think we've discovered an approach that suits most developers and teams yet.
