Struct TimestampPolicy 

pub struct TimestampPolicy { /* private fields */ }

Timestamp validation policy

Validates timestamps in provenance data to prevent:

• Time-based attacks (using old vulnerable versions)
• Timestamp manipulation to hide malicious activity
• Future-dated timestamps (clock skew attacks)

Implementations

impl TimestampPolicy

pub fn new() -> Self

Create a new timestamp policy with default settings

• No maximum age limit
• 5 minutes future tolerance (for clock skew)
• Timestamps required

pub fn with_max_age_seconds(self, seconds: i64) -> Self

Set maximum age for timestamps Compositions/builds older than this are rejected

pub fn with_max_age_days(self, days: i64) -> Self

Set maximum age in days

pub fn with_future_tolerance_seconds(self, seconds: i64) -> Self

Set future tolerance for clock skew

pub fn require_timestamps(self, require: bool) -> Self

Set whether timestamps are required

pub fn validate_timestamp( &self, timestamp: &str, context: &str, ) -> Result<(), String>

Validate a timestamp string (ISO 8601 format) Returns Ok(()) if valid, Err(String) with reason if invalid

pub fn validate_optional_timestamp( &self, timestamp: Option<&str>, context: &str, ) -> Result<(), String>

Validate an optional timestamp
