Yeah, Sun moves with velocity about 230 km/sec relative to Milky Way center. So if you launch a rocket in opposite direction with the velocity -230 km/s, it will stay still (relative to Milky Way core). But because 230 km/s is way less than the speed of light 3x10^5 km/s, practically no time dilation will take place: t'/t=sqrt(1-(230/300000)^2)=.99999971 =99.999971 % or about one second off in 40 days.

Even if you move with a speed very close to the speed of light, you can not travel back or forth in time.
