If you want to get into the nitty gritty of that then YES, Hawking isn't being careful when he speaks about the beginning of time as we know it.
In fact, I would love to sit down with Hawking himself ad discuss this very topic because he is indeed making an error here.
1. Hawking admits to starting with QM.
2. Quantum Mechanics demands that things change.
3. Things cannot change without time being a component.
Therefore, Hawkings universe is not the beginning of
time as he claims.
In fact, Hawking should know. He most likely does know better. And this is why I would like to sit down and discuss this topic with him. I'm sure that once I explain my views he will agree with me on the details.
Here's my view.
In the Quantum World time is non-entropic. That is to say that it is not tied up with entropy. It can't be. There is no entropy in the Quantum World. But there is change. There may not even be such a thing as "space" in the quantum world. That is a more difficult thing to know. But if there is such a thing as "space" in the quantum world it is not tied together with "time" (i.e. with change).
Now when the macro world comes into being time and space because intimately entwined. They become dependently entangled. And we end up with Einstein's observation of what we call a "fabric" of
spacetime. Spacetime has a property of entropy. In other words, the time (or process of change) that has become entangled with space has become
entropic time (change that is dependent upon entropy).
So Hawking is actually wrong if he claims that "Time" began with the Big Bang. This is, of course, absolutely true if he's starting with the postulate that the laws of QM are already in place. Which is indeed one of his foundational premises.
So he's starting "time" (things changing) in the quantum realm. And "time" (things changing) does not begin with the Big Bang. But what does happen during the Big Bang event is that "Time" (things changing) becomes entangled with space in a way that produces a fabric of
spacetime that has entropic properties (i.e. it obeys the law of entropy).
If Hawking wants to be more precise in this description he should say that "Entropy" began with the Big Bang. Not that
time began with the Big Bang.
So yes, I do have a bone to pick with some of Stephen Hawking's claims and jargon. And I think if I sat down with him and explained my concerns he would see where I have a point. He might then be more careful in his claims.
It's not necessarily that he outright wrong. He's just not paying attention to the subtle details and he's being sloppy in his language and claims.
I hold that the following conditional statement is true:
IF a person begins with the postulate that a Quantum Field of potentiality exists (which Hawking does) THEN they cannot say that time came into being with the Big Bang, they can only say that an interdependent fabric of spacetime arose.
In fact to be more accurate what they should really be saying is that entropy came into being with the Big Bang. Not time. Time was already postulated to exist when the postulate of a Quantum Field of potentiality was included as a premise. It just wasn't yet entangled with space in a way that produces entropy.

Personally I find this particular observation to be quite interesting because it begs the question of whether or not the very concept of space itself has any meaning in the quantum realm at all. Do space and time both exist in the quantum world but they are simply not yet entangled to create entropy? Or is there no space in the quantum realm at all? Perhaps it's only space that is created in the Big Bang. And as it is created it is created in such a way to make it intimately dependent upon time (change) so that it must then unfold in a way that obeys the thermodynamic law of entropy.
So for me, this is a very interesting scientific question in general. One that hasn't truly been address insofar as I know. I do know that Paul Davis touched on this in his book "About Time". But that book is fairly old now and the concepts that Paul Davis addresses in his book need to be re-visited.
Other people have addressed these idea too in passing. I think Lee Smolin addresses this in his book "Three Roads to Quantum Gravity". And Sean Carrol might address it also in his book, "From Eternity to Here". But non of them address it in great depth. Possibly because there simply may not be any way to get at the answer scientifically.
