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.

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