A clock is not some cosmic gas meter "measuring the flow of time". It merely features some kind of cyclical local motion which is counted or accumulated and shown as "the time". Also see Is time an illusion? and Is this one of the reasons we can't travel in time?. | |

Duplicate of understanding time: Is time simply the rate change?, Is there a proof of existence of time? | |

| Aug 3, 2015 at 17:28 | comment | added | Insert Pseudonym | @JohnRennie Your answer to that question was perfect. This is therefore a duplicate of "Is there a proof of existence of time?". | |
| Aug 3, 2015 at 17:25 | comment | added | Insert Pseudonym | @KyleKanos I don't think you understood what I meant. I suppose I am referring to the flow of time. It's not flowing relative to any other parameter even though we can hypothetically change the direction of the flow (the example of backwards time travel, as I noted). In other words, when the other spacetime dimensions change we can describe this change with the velocity concept(ie. as a function of time) but we cannot do the same with the fourth dimension, time (in other words, describe time-flow).Also the question you linked wasn't helpful (the other one by John Rennie, though, was). | |
| Aug 3, 2015 at 17:01 | comment | added | Kyle Kanos | What, then, measures the rate at which time changes? is nonsense. Rate is something that changes with time, so you are asking "How does time change with time?" which doesn't make sense. | |
| Aug 3, 2015 at 14:36 | comment | added | user81619 | Also, you could Google "supertime", which, I think, addresses your question more deeply than you may find on this physics question and answer site. Just be careful, there are lots of references to a video game with the same name. Best of luck with it | |

| Aug 3, 2015 at 13:58 | comment | added | user81619 | This is an old, old philosophical question, in physics the view is taken that time is that which you can measure by a clock, pragmatic as it sounds. | |
