That really depends on what you mean with real thing, I would say our understanding of time and space is heading towards them being emergent phenomena and not fundamental ones. As far as we know, there is no thing in the universe called the time that you can just measure, you can only look at the ordering of events. And then we invent a variable called time that lets us express the laws of physics reproducing the observed events in a simple way, but that is much more a convenient mathematical and everyday tool than a real thing than one usually realizes.
