Kant may have deducted that, but he's talking about a neurobiological phenomenon born from evolutionary pressures in a very limited environment.
Michelson–Morley mesured, and Einstein explained, how speed of light, not time, is constant through the Universe. To the point of questioning simultaneity.
If we've already got non-constant time, then the concept of a time origin prior to which there is no sensible physical description is at least plausible, if not something I can, spacial geometric puns pardoned, wrap my brain around in the same sense that there's a limit to "northness" on a spheroid.
