Actually these things happen all the time, now, in the real world but on such a tiny tiny level that we'll never notice them, only at a universal level do they have any real significance.
Example 1, set two atomic clocks at exactly the same time, give one to Priya Rai and put her on a flight around the world non stop. Give the other to..... me
and then when me and Priya meet up the clocks will be out of sync, Priya's clock will have travelled into the future, all be it millionths of a second.
Example 2, Alexis Silver is oiling up her boobs 10 meters away from me and that damned annoying Priya Rai that can't leave me alone is masturbating 50 meters behind her. Although I can see both of them together, neither of them are actually in the same time as me, both events happened at different times in the past. Again millionths of seconds.
