"In 1915, Albert Einstein first proposed his theory of special relativity. Essentially, this theory proposes the universe we live in includes 4 dimensions, the first three being what we know as space, and the fourth being spacetime, which is a dimension where time and space are inextricably linked. According to Einstein, two people observing the same event in the same way could perceive the singular event occurring at two different times, depending upon their distance from the event in question. These types of differences arise from the time it takes for light to travel through space. Since light does travel at a finite and ever-constant speed, an observer from a more distant point will perceive an event as occurring later in time; however, the event is "actually" occurring at the same instant in time. Thus, "time" is dependent on space." Read more here: http://library.thinkquest.org/06aug/02088/einstein.htm
Yep. I don't see how we can understand that position and gravity alter our perception of the sequence of events and then wonder if time is emergent. Of course it is. Time is a variable, and it's affected by relative velocity and gravitation. What is 'fundamental' mean in this context anyway?

Of or relating to the foundation or base; elementary: the fundamental laws of the universe. Basically, the basics.
