Clocks in space

[Mellow Matt]

If you had 2 synchronised atomic clocks, and sent one up into space, then brought it back, would they still both still be in synch...?

This is messing with my mind...!

OK, so if you have a clock on the ground, and put another in a geosynchronous space station (so the space station will be travelling faster in order to stay above the same bit of Earch), and then bring the space clock back down after years and years, would the clocks be out of synch?

Also, does it matter what type of clock it is (other than the fact that an atomic clock will be more accurate)? (I don't think it matters, but my workmate is insisting it does!).

Thank you guys, I will now go and act smug to everyone

Thanks for the offer, but I think I get it now, I just needed someone to confirm as I was doubting myself...!
