Quantum mechanics and Einstein's relativity. Both are pillars of 20th-century physics, and, as pillars go, these scientific fields stand opposite of each other, at least when it comes to the concept of time.
When derived from quantum mechanics, time is a parameter that is ever-flowing at a constant rate. When derived from relativity, however, time can be seen as something relative from two observers. So what really is time?
"We don't know," Martin Bojowald, a physicist at Pennsylvania State University in University Park, told Live Science. "We know that things change, and we describe that change in terms of time."
But it seems that we're now closer to reconciling the conflicting concepts of time through this new theory of a universal clock.

One of the funny things about time is that, as humans, we think we "have time". But we really don't, do we. It's the other way around - time has us. That's why, if you have any worthwhile goals you've been putting off, you need to go ahead and do those things. Because you don't really have time. None of us do. Get out there and do stuff and be happy. :>
