pub fn with_clock_skew(self, clock_skew: ClockSkew) -> Self

Set clock skew tolerance for SAML time windows.

pub fn with_replay_retention(self, retention: Duration) -> Self

Set explicit replay retention for protocol messages that do not carry a SAML NotOnOrAfter value suitable for cache expiry.

pub fn now(&self) -> SystemTime

Validation instant supplied by the caller.

pub fn clock_skew(&self) -> ClockSkew

Clock skew applied to time-window checks.

pub fn replay_retention(&self) -> Option<Duration>

Replay retention for protocol message IDs without SAML expiry.
