SWT/Space Layer

Simplified World Time (12 zones), Tiles, and Long-Cycle Calendar (T_cyclezero)

Status: Official Spec

DOI: 10.5281/zenodo.18070000

Abstract

This document specifies the Timeverse Space Layer, defining: (i) SWT (Simplified World Time) as a 12-zone public context label suitable for human interfaces (HTIL/T-Watch/Tilemedia), routing domains, and audit scoping; (ii) Tiles as deterministic identifiers for community feeds, moderation scope, routing, and provenance organization; and (iii) a D-Calendar projection using a long-cycle period 𝑇_cyclezero (Earth-first profile) for human-friendly calendar decomposition. SWT/Tiles/D-Calendar/capsuletime/compass fields are public context and MUST NOT change tick-canonical execution semantics. Canonical execution remains governed by convention_id and tick fields as defined by the Phase-Coordination Conventions.

1. Scope and non-goals

Principle 1.1 (Space Layer is context, not execution): SWT zones, tile identifiers, D-Calendar fields, capsuletime strings, and compass labels are context/UI. They MUST NOT modify canonical execution semantics (cycle anchoring, ticks, window membership) which remain defined by convention_idand tick-canonical fields (per Conventions).

Principle 1.2 (Context is not secret): SWT/tile/calendar/capsuletime/compass fields are public context and MUST NOT be treated as secrets.

2. SWT: Simplified World Time (12 zones)

Definition 2.1 (SWT zone identifier):

Under swt_schema_id=TV-SWT-12Z-2025-12, an SWT zone is an integer:

swt_zone ∈ {1,2,...,12}

Definition 2.2 (Informative UTC-offset set label):

SWT zones MAY be presented as a simplified set of two integer UTC offsets:

offsets(z) := {2z-25, 2z-24} hours (modulo 24), z∈{1,...,12}

Example: SWT12 corresponds to {0, +1} (Baseline). SWT6 corresponds to -12 hours. This set is a display label and MUST NOT define protocol arithmetic.

Remark 2.1 (SWT12 is the Reference): In Timeverse Protocol v4.6.2, SWT12 serves as the prime meridian (Offset +0).

3. Tiles: deterministic identifiers (600 tiles)

Tiles are partitioned across the 12 SWT zones. SWT12 contains the terminal set of tiles (551-600).

Definition 3.3 (Canonical tile identifier string):

A canonical tile identifier string is:

tile_id := "swt="swt_zone";tile="tile_global

4. D-Calendar: long-cycle projection with T_cyclezero

The D-Calendar remains synchronized with the T2° kernel. The long cycle (CycleZero) increments every 30 years.

Conclusion

The Space Layer establishes SWT12 as the canonical zero-offset zone. This alignment ensures that all Timeverse Sovereign Nodes, AI agents, and Quantum schedulers operate from a unified spatiotemporal baseline.
