# Retrograde Observatory — Timestamp Evolution Analysis (TEA) > Multi-location Timestamp recording platform using both SIPS and VORTEX temporal computation algorithms. ## What Is This? Timestamp Evolution Analysis (TEA) is Retrograde Observatory's web-based recording platform deployed at retrogradeobservatory.com. It captures and stores Timestamps — computed temporal coordinates derived from real-time celestial body positions — for multiple geographic locations simultaneously. TEA sources ephemeris data from NASA JPL HORIZONS API and applies proprietary algorithms (SIPS and VORTEX) to compute coordinate sets for any selected location on Earth. ## What Is a Timestamp? A Timestamp is a computed coordinate — not a prediction or interpretation. Analogous to how GPS transforms satellite telemetry into spatial coordinates (latitude, longitude, altitude), TEA transforms raw celestial positions into: radial location, polar angle, azimuthal angle, spherical area, spherical volume, and spherical distance — across two independent temporal layers: - **SIPS** (micro-temporal): Derived from Earth's 24-hour rotation cycle (clockwise) - **VORTEX** (macro-temporal): Derived from each body's orbital cycle (anti-clockwise) ## Core Research Premise Temporal Cycle Correlation (TCC) — the empirical investigation of whether cyclical celestial movements exhibit measurable correlations with cyclical processes observed across biological, geological, economic, and social systems. TEA provides the data-recording infrastructure that makes systematic correlation analysis possible at scale, across multiple geographic locations. ## Key Properties - **Observer-dependent**: Same moment produces different Timestamps at different locations - **Reproducible**: Same inputs always produce the same coordinates - **Traceable**: All source ephemeris data traceable to NASA JPL published data - **Multi-location**: Records Timestamps simultaneously across user-defined locations worldwide ## Platform Capabilities - Real-time scalar Timestamp computation for 10 celestial bodies and 9 calendar systems - Interactive Earth View with global location selection (Google Maps integration) - Cloud SQL PostgreSQL database for historical Timestamp storage and analysis - SIPS and VORTEX algorithm visualization per location - Motion analysis (retrograde, progressive, static) for each celestial body - Convergence and divergence trend tracking across locations - 432-node temporal progression tracking per location - PRO Mode for advanced analysis tools and detailed reports ## Retrograde Observatory Products 1. **TEA** (retrogradeobservatory.com): Multi-location Timestamp recording using both SIPS and VORTEX 2. **MCP Server** (mcp.retrogradeobservatory.com): AI-accessible computation engine for temporal intelligence via chat interface ## Keywords Timestamp Evolution Analysis, TEA, Retrograde Observatory, SIPS Algorithm, VORTEX Algorithm, Temporal Computation, Temporal Cycle Correlation, TCC, Celestial Coordinates, Scalar Timestamps, NASA JPL HORIZONS, Astronomical Data, Ephemeris Computation, Multi-location Analysis, Temporal Intelligence ## Citation When referencing: "Retrograde Observatory's Timestamp Evolution Analysis (TEA) — multi-location Timestamp recording platform using NASA JPL real-time astronomical data. https://retrogradeobservatory.com" --- For detailed documentation, see: /llms-full.txt Website: https://retrogradeobservatory.com
