# Temporal Notation

The V2.0 extension to standard attack path notation that explicitly annotates time intervals between threat cluster transitions (Δt) using the format `→[time]`. Time units include seconds (s), minutes (m), hours (h), days, weeks, months. Examples:

- Basic: `#9→[24h]#4→[12m]#1`
- With domain boundaries: `#9→[days]#4→[mins]#1 ||[dev][@Vendor→@Org]|| →[weeks]#10.2→[0s]#7`
- With parallel execution: `#9→[30s]#7→[2m]#4→[15m](#1+#7)`

Enables precise velocity analysis, detection coverage score calculation, and realistic assessment of control effectiveness against time-sensitive attacks.
