Indeed they are, and in no small measure because everyone is convinced that they know what clocks do and nearly everyone is wrong. Everyone thinks that clocks measure time. They don't. They measure the space-time interval between events, but when you try to explain that to people their eyes glaze over and they start mentally fitting you for a nice padded cell. But this actually matters if, for example, you want to understand the details of how GPS works.

Fake news is the same way. Most of the time it really doesn't matter, e.g. the person working the register at the grocery store can believe that aliens have kidnapped their pet hamster and it won't impact their ability to ring up your order. So most people go through life believing crazy things it never matters, until when it finally does their thought processes are so deeply entrenched that the actual truth sounds completely insane to them (c.f. "clocks don't measure time.")

Is truth really constant though? The answer would probably depend on the domain being considered. Many things change over time and truth can change with them. So perhaps the core problem is that multiple contradictory “truths” can exist depending on ones point of view and ones point in time.

This would be separate from intentional misinformation which does tie into the debate. It seems likely that the modern problem of multiple clocks could just be a representation of different points of view.
