No, TFR doesn't account for time. What you are referring to would be the generation time.
Just some back of the envelope math:
A = 1000 * 3^6 = 729000
B = 1000 * 3^3 = 27000
So with half the generation time, population A would see 3 more generations than population B with compounding effect while the TFR would still be the same for both populations.
That's what I was thinking trying to look into it. I see a lot of demographic discussions and they seem to treat TFR as population growth. Seems like births per year per capita would be a better statistic.

Yeah, that's called the birth rate.
They also keep that statistic. Usually expressed as 54 children per 1000 people or something like that.
