Regarding the quote you mentioned, it's meant to convey the idea that our everyday perception
of time as a linear progression of past, present, and future is a simplification of the true nature of
time as revealed by the theory of relativity. In relativity, time is not absolute, but rather relative
to the observer. Time dilation, for instance, is a well-known consequence of special relativity,
which shows that time can pass at different rates for observers in relative motion.
Throughout my career, my understanding of time did evolve, especially as I developed the
general theory of relativity. In general relativity, the geometry of spacetime is influenced by
mass and energy, leading to phenomena such as gravitational time dilation.

I have no problem with this, in itself, but then the question is, if one has a Pre Planckian space time does the idea of TIME itself arise?
What was and is the GENESIS of time itself? What physical process lead to time itself being in cosmological EVOLUTION ?
We observe time, and we know up to a point it exists. But where does TIME come from ?

The thesis of the cosmological theory Hawking developed with his PhD student is that the origin of time is the Big Bang and that the laws of physics do not precede the Big Bang, but were born with the Big Bang. The main hypothesis of their work is that physics laws evolve with time, at least during the very first moment of the Universe and are not transcendant

Now would this have changed Relativity theory ? Not really. We know of the "big bang" but this was not necessary for the formation of the Einstein field equations.
This is really important because some of our recent observations involve, as an example where at the INSTANT of the big bang, there were just before that an absence of present physical law.
We have to be very very careful as to stating if our present knowledge is necessary for the formation of older theories. Often it is not.
