How long was Chris in Sonic's world?

[Petzbreeder]

I haven't seen Sonic X for ages, but something has been bothering me.

There was a 6 year time skip after Chris and Sonic parted ways. When Chris enters Sonic's world, he discovers that only 6 hours had passed. How long was Chris in Sonic's world? I'm just trying to work out how old he would have been when he returned home.

Too long

 I wasn't there very long, they didn't have a Poundland so I couldn't get any of those Strawberry Softies
