YEAh yeah yeah " A-theorists also appeal to the fact that our temporal experience strongly suggests that time is dynamic." https://www.rep.routledge.com/articles/thematic/time-metaphysics-of/v-2/sections/the-b-theory-and-temporal-experience
"strongly suggests" . how about... the alternative is logically impossible.
There are two options: The self having an experience at 12pm flows to the next moments, or the self does not flow to new experiences in the next moments.
The B theorists deny that anyone flows to a new experience, SO the self must simply experience 12pm eternally. But eternally may sound wrong because it can be interpreted as everlasting. Timeless might sound better, like how people say that if numbers existed, the numbers could be called either "timeless" or "eternal."
I concluded that the self must be eternally in that experience at 12pm, because there is no other conclusion.
There's already evidence that some people don't experience time. The only thing to do now is determine who.
For example Bernardo Kastrup keeps saying he's not conscious of anything existing or anything happening, only conscious of the NOTHING . He even wrote an article for Scientific American saying he doesn't experience a flow of time.

Bernardo Kastrup part 2: "And I think it's true. That's the magic of existence. Nothing ever happens. Nothing ever happened. Nothing will ever happen." https://youtu.be/BG31Oz0VWmI?t=2893
