Time exists in theroy is what I am saying. Yes it can be measured, becuase that is what it is, a measurement made by us to (like measurments in weight and lenght) help us understand things better.
P.S. I am not a very good speller. Sorry if i misspelled somthing.
Time might be seen as a special kind of dimension. To specify a point in an unambiguous way you have to specify it's spatial coordinates and time (and the universe index
). In other words it's a characteristic of every point in time-space continuum, that cannot be ignored in physics, just like energy/mass, speed, charge, rotation, gravity field, electric field, magnetic field, etc.
It exists in the same way mass exists. The funny thing is that even vacuum exists (

Maybe you have some different definition of existence?
