The date on his contract should be the date he ships or close to it since sometimes there is a need to move some to a different date. If he agreed to take an earlier date, then he could be called up earlier if someone else with the same contracted rating or field is unable to ship for some reason, but others may also be offered that spot and may take it. so even if the recruiter thinks he got the date, then it is not always a done deal depending on which one was entered first.
