Looking for a fic I read several years ago.

[lothiriel_mae]

The fic I'm looking for is a Jack/Sam fic where they were shot out the wrong gate and ended up in another galaxy. I remember that the Gate system there was an older version, so every time they went through the gate they got slightly younger. They spent years(?) trying to get home and when they got back to the SCG they were noticeably younger and Sam had long hair(?) and it turns out that what was years for them was almost nothing for Earth.

I think I read it on fanfiction.net, but I swear it had to have been more than 15 years ago. I appreciate any help you can give.
