OFS does not change Earth’s rotation, seasons, or ISO/UTC. It changes the interface used by humans and systems to coordinate: ISO/UTC remains authoritative; OFS adds a deterministic daily display token (Civil), a system ordering pulse (FT), and optional semantics (MT).
"." is a separator, not a decimal point. Φ ranges 0–9. ψ ranges 00000–09999 (fixed 5 digits).
Why 1Φ = 10,000ψ?
It is a normative resolution choice: large enough for machine scheduling and smooth UI, small enough to avoid precision-driven surveillance pressure. The standard treats ISO as authoritative; Civil is an interface.

OFS Civil uses a mean-day interface baseline (86,400 seconds/day) for stability. UTC leap seconds may produce an 86,401-second day; implementations may smear or map the extra second. ISO/UTC remains authoritative; OFS is an overlay.
