Signature date 10 is the date when a software is signed, specifically, the year and month of the Gregorian calendar 10.

Signature, that is, writing one's own name, especially used to express agreement, recognition, responsibility or obligation, has more explanations, such as digital signature and artistic signature. Or a meaningful signature of a star, also called a signature. Signature is a kind of signature, because it is used the most, so it is often mistaken for signature.
