No Einstein did not propose time did not exist. Time exists only in a space time continuum.

That means nothing. People like us, who believe in physics, know that the distinction between past, present and future
is only a stubbornly persistent illusion. Einstein did not reject the existence of time. Instead, he rejected the distinction between past, present, and future.
Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.
The continuation of Einstein's Theory of Relativity, and the space time continuum is that in the Quantum World without the three dimensional space time continuum of our universe time does not exist.
