If there was one clock for everyone we'd all trust the time and agree on it. When everyone carries around their own watch, we all have somewhat different times, and trust it and agree on it less. Now we each have access to thousands of clocks at the click of a button. They report wildly inconsistent times. Poll: Do you trust the time tellers? Response: A lot less than I used to. According to special relativity, the time for you is path dependent, and different than for everyone else depending on the vectors that brought you to this point. If two times are inconsistent it doesn't necessarily mean that either one is wrong.
