since your character did start with the 1.0, your character didn't have aged since you was send throught time, for you no time did pass. it's impossible to know how many time did pass in the V1 since the story did change in middle. the timeline was the one for the V1 before yoshida. but almost everything was changed, even the ascian. the safest guess is your character throught the V1 did age of 1-2 years (time of the v1) and 1-2 years for ARR.

when you travel throught time, your age don't change, then.... *shrugs* other point important, we don't know how old live most of the race from eorzea, then it don't have a lot of importance, no?
