Not necessarily; but it certainly could be. Certainly the two are sufficiently similar infinities for us to accept this for the sake of argument.

They are the EXACT SAME THING, in terms of the amount of time.
What you say about A, in terms of the amount of time, you also say about B.
If B represents time that never finishes so does A.
Which is an amount of time that can't finish at the present. It is an amount of time that never finishes.
An infinite future never finishes; by analogy, an infinite past never starts. The reason one is called 'the future' and the other 'the past', is precisely that the former starts at the present, and the latter finishes at the present. The thing stopping an infinite future from finishing, but not stopping it from starting, is that it is the future; if we take the same amount of time in the past, then it is impossible for it to have a start, and necessary for it to have a finish for the exact same reason.
The thing stopping an infinite future from finishing is that it is infinite, not that it starts at the present. Finite time could also start at the present.
Indeed it could.
But infinite time in the past could not finish at the present because it is like infinite time in the future.
It is like infinite time in the future in that it is bounded by the present, as your graph clearly shows; and in that it is infinite, as your graph also shows.
I can SEE it finishing, at the present, on YOUR graph. That is what defines it as the past.
I agree it changes nothing. It simply shows what is going on.
Then why raise it - it is just muddying the waters.
No, it is clarifying muddied waters. It is very muddy to talk about things that don't start.
Don't be silly. The phrase 'infinite past' means 'time with no start'. Call it 'amount of time' or call it 'time', either way it has no start if it is both a) infinite; and b) the past. By definition.
It is much cleaner to talk about something we understand. An amount of something.
Well if you like we can talk about something completely unrelated to the topic, but that we both understand. That would be a short, boring and pointless discussion though.
An infinite amount of time won't finish no matter how much of an opportunity you give it. Just like counting the negative integers won't finish even if you had infinite time.
It will, if you are now at a defined point, and counting towards zero. And the only way to have achieved that is to have already been counting for an infinite amount of time.
No. You will not finish counting the negative integers no matter how much time you have.
Unless the amount is
infinite. That's pretty much what 'infinite' means.
If every prior second represented a negative integer you would never finish them to get to the next second if they were infinite.
Where do you imagine we are starting this counting from?
If in the future it is an amount of time that will never finish
...because by definition the future starts at the present...
Again, it is an amount of time that never finishes because it is infinite, not because it starts at the present.
...and again, if it starts at the present, it is called 'the future'.
it is that same amount of time in the past.
...and as the past, by definition, finishes at the present, it will, if infinite, never start. Hence the 'start' of the past, like the 'finish' of the future, not actually appearing on the graph - they can't because they cannot ever be reached in finite time.
The past is time that has already past.
Yes.
If it was infinite it would be an amount that never finishes.
NO. All thumbs are fingers, but not all fingers are thumbs. All amounts of time that never finish are infinite, but not all infinite amounts of time never finish.
An infinite amount of time is an amount
that is unbounded at one or both ends.
IF it never finishes, but does start, then it is called 'the future';
IF it it never starts, but does finish, then it is called 'the past';
and IF it neither starts nor finishes, then it is called 'all time'.
Your statement "If it was infinite it would be an amount that never finishes" is simply not complete. It is but one (or two) of the three possible scenarios if something is infinite. You have no grounds to rule out the other way an amount of time can be infinite - by being an amount that never starts.
You keep making the same error over and over again.
You are making the error of claiming that one of three possible ways for 'an amount of time' to be infinite is the only possible way. It isn't.
You somehow think saying time that doesn't start means a different amount of time from saying time doesn't finish.
Not at all.
They are the exact same amount of time.
Yes.
If one never finishes neither does the other.
NO. There is more than one way for them to be the exact same amount of time, and 'never finishes' is only ONE of THREE possibilities. You can't just pretend the other two options don't exist.
It is a good graph; it shows exactly how the infinite past and infinite future are reflections about the present; and it shows that there is nothing particularly different about the two concepts. Both are bounded at one end only; Both are bounded by the present; Both are infinite. The only difference between them is the direction you look from the present in order to see them - if you look back, the infinite time is called 'the past' and if you look forward, it is called 'the future'.
They are the SAME EXACT AMOUNT of time. If one is time that never finishes, so is the other.
NO. There is more than one way for them to be the exact same amount of time, and 'never finishes' is only ONE of THREE possibilities. You can't just pretend the other two options don't exist.
All thumbs are fingers, but not all fingers are thumbs. All amounts of time that never finish are infinite, but not all infinite amounts of time never finish.
An infinite amount of time is an amount
that is unbounded at one or both ends.
IF it never finishes, but does start, then it is called 'the future';
IF it it never starts, but does finish, then it is called 'the past';
and IF it neither starts nor finishes, then it is called 'all time'.
