According to the theory, when the two watches are brought back together, one should be chronologically behind the other.

It's worthwile mentioning that the theory has been experimentaly tested and confirmed.

Re: Calculation

No. ds^2 can be either positive or negative, depending on which of dt and dx is bigger. But note that wheather ds^2 is defined as

ds^2 = dt^2 - dx^2

or as

ds^2 = -dt^2 + dx^2

is a matter of convention
