Validity

Validity specifies the period of time during which a certificate is valid. Validity can be expressed as an explicit date and time when the validity of a certificate starts or expires, or as a span of time after issuance, stated in days, months, or years. For more information, see Validity in RFC 5280.

Amazon Web Services Private CA API consumes the Validity data type differently in two distinct parameters of the IssueCertificate action. The required parameter IssueCertificate:Validity specifies the end of a certificate's validity period. The optional parameter IssueCertificate:ValidityNotBefore specifies a customized starting time for the validity period.
