how long for fruit tree to bear from rooted cutting?

[organik]

i'm getting some cuttings from a mature longan tree. it's fruited sporadically over 10 yr period. its over 30 yrs old. how long will it take to fruit if i get a cutting?

Mine took about 1 year to fruit from an air layer but I heavily watered and fertilized, more likely 2+years under normal conditions.

These are from this years crop, my tree has now been in a the ground about 2 years if I recall correctly.
