I used the DC Comics guide (http://www.dcuguide.com/Who/Batman_Bio.htm) plus information from DK publishers. They have Bruce going overseas at 14, starting in England and moving on from there, eventually ending up in Japan, and returning to the states 12 years later. I've verified the 12 years abroad in several places (like here (http://www.darkknight.ca/heroes/batman.html)), however, I have found his leaving age to be as young as twelve, which gives my information at +/-2. I have a few other sites that I can't get at, at the moment (stupid computer), but will add on to this post once I get them.
