so from what I learned, in TDKR which is set in 1986, Bruce is 55, so 1986-55 = 1931. So let's see when his parents were killed 1931+8= 1939... ok this is so meta. anyways Year One is set 30 years before TDKR, so 1986-30= 1956, this means that his 12 years of training started in... 1956-12= 1944.
So let's do a simmary
1931 - Bruce Wayne is Born. (0)
1939 - Thomas and Martha Wayne are killed (8)
1944 - Bruce starts his training (13)
1956 - Year One. (25)
1986 - TDKR (55)
ASB&R reveals smt new, he wasn't 8 like other adaptations, but 6.
So let's change all the dates. And add the fact that the death of his parents happened 19 years ago, making him 25. So 1931+25 = 1956 oh...
so uhm... Nothing changes aside from Bruce's past.
1931 - Bruce Wayne is Born. (0)
1937 - Thomas and Martha Wayne are killed (6)
1944 - Bruce starts his training (13)
1956 - Year One. (25)
1956 - ASB&R (25)
1986 - TDKR (55)
Last crusade is easy as it takes place 10 years before TDKR, and all the sequels have stated years so we've got!
1931 - Bruce Wayne is Born. (0)
1937 - Thomas and Martha Wayne are killed (6)
1944 - Bruce starts his training (13)
1956 - Year One. (25)
1956 - ASB&R (25)
1976 - Last Crusade (45)
1986 - TDKR (55)
1989 - TDKSB (58)
1992 - TDKMR (61)
1995 - Golden Child (64)
So we've got a problem for ASB&R.
