Ds^2 Invariant Interval: Sign Dependence?

[binbagsss]

Some sources have $ds^{2}=d\tau^{2}$, and others have $ds^{2}=-d\tau^{2}$,
Does the sign depend on the signature chosen for the metric?

Thanks in advance.

 

[Nugatory]

Yes.

 

[binbagsss]

Yes.

Thanks, and just to confirm a $(+,-,-,-)$ signature has $ds^{2}=d\tau^{2}$ and a $(-,+,+,+)$ signature has $ds^{2}=-d\tau^{2}$?

Yes. I prefer the second convention. (-+++)
