timestamp

The timestamp indicating when the fact was created or stored, expressed as the number of milliseconds elapsed since the Unix epoch (January 1, 1970, 00:00:00 UTC).

This property is crucial for enabling temporal reasoning within the memory system, allowing the system to associate facts with specific moments in time. It is used for:

• Ordering facts chronologically

• Supporting time-based queries and operations

• Tracking data validity or freshness based on creation time

This value is typically generated using a platform-specific implementation of the TimeProvider interface to ensure precision and consistency across different platforms.
