If you wanted to be *that* pedantic, you could argue that “all time” technically doesn’t include future time anyway, by the very fact that he hasn’t happened yet. I’m sure the theoretical physicists or string theory experts (or whatever) can confirm
Well now, going off topic, but if you want to go that route.
The concept of time is simply an illusion made up of human memories, and misled by human perspective.
In reality, everything that has ever been and ever will be, is happening right now, at this instant, and at every instant, that has ever been, and will ever be.
Think of the block universe, which is supported by Einstein's theory of relativity, as a four-dimensional space-time structure where time is like space.
In that universe, every event, that has happened or will ever happen, has its own individual coordinates, or address, within space-time.
Time is tenseless, all points equally "real," so that future and past are no less real than the present.
In the words of Physicist Max Tegmark.
"So life is like a movie, and space-time is like the DVD.
There's nothing about the DVD itself that is changing in any way, even though there's all this drama unfolding in the movie. We have the illusion, at any given moment, that the past already happened and the future doesn't yet exist, and that things are changing. But all I'm ever aware of is my brain state right now. The only reason I feel like I have a past is that my brain contains memories."
