If Jin went BACK into the past...then he would not affect the future. It made me think that if there was a time machine it would go back and then leave the present altogether. The present would then not have happened...if that makes any sense. So when Jin returned he would return to the same time that he left. Not six years at all. This has bothered me and I don't know if I have made clear what I have been thinking regarding the time situation.
Any thoughts??
I'm guessing buymethisdress hasn't watched JIN 2 either.
So you're asking if he returns to the same point he left, or if six years will have passed in the present as well? You ask this in a weird way. The present still happens whether he's there or not. That's like asking "if a tree falls in the forest and no one's around to hear it, does it still make a sound?" Yes, it does. But what we're talking about here is the much more theoretical issue of time travel. What you want to know is, if he lives six years the past, will he "skip" six years of the present? To answer this, I will have to spoil you, if you haven't been totally spoiled already.
Here's the simple answer which should allow to figure it out yourself:

Remember the man Jin operated on in the first episode of season 1? That wasn't Sakamoto Ryoma. If you didn't already figure it out, that was Jin himself. Or rather, a version of Jin.
To go into more detail, requires more spoilers! Read on if you want the full explanation.

They explain this in the last episode of JIN 2. Yes, he went back in time, but by going into the past he created a parallel world and it was there that he lived and changed things. When he returned it was to the present of that parallel world and not the world he left from, so he could see the changes he made. Those changes were: Miki was born but with slightly different ancestors and she never became a doctor thus she never met Jin (why the photo never returns), penicillin is recorded to have been first made in Japan, and Japan established medical insurance back in the 19th century (this is a minor part of the plot of season 2). As I said, the man Jin operated on in the first episode of season 1 was actually another version of himself, from a parallel world, which I guess replaced him in Jin's original world. When our Jin returned he actually watched another Jin go through the time slip, confirming his suspicions. But thanks to the corrective power of time, which is what Jin thinks gave him the headaches, erases Miki's photo, and so on, no one remembers Jin's existence in the past. After the second Jin leaves, in the present no one remembers there being 2 of Jin at one point. This is how the show gets away with all this history-changing. So basically, Jin is involved in a potentially infinite creation of parallel worlds, each changed ever so slightly until... who knows? But no one will ever know, and perhaps even Jin himself will one day forget he ever slipped back to the Edo period. And everything is balanced out by the universe itself, which erases the memory of Jin's time slip but not the changes he made, so everything balances out and order is maintained.
@buymethisdress: I doubt anyone would notice he'd aged, because he wouldn't have aged significantly. Six years isn't really that long of a time. Plus, most people would attribute rapid ageing to stress or illness, because that's logical.
To answer your question, read the second spoiler. Put simply, it's magic. He does change the past and thus effects the present, but magically he's the only one who remembers doing any of it. ;)
