This study extends the Global Time Echoes program to 25.3 years of GNSS timing data, analyzing 30-second clock products from the CODE analysis center (2000–2025; 814 stations; 165,198,849 station pairs). Distance-structured correlations previously identified across independent analysis centers remain stable over decadal timescales, with persistent east–west > north–south anisotropy (strength = 1.981 ± 0.23; p < 10⁻¹⁵). This analysis builds on the initial multi-center study (Global Time Echoes: Distance-Structured Correlations in GNSS Clocks, https://doi.org/10.5281/zenodo.17127229) and follows the theoretical framework introduced in the Temporal Equivalence Principle preprint (https://doi.org/10.5281/zenodo.16921911). A strong annual modulation correlated with Earth’s orbital velocity is observed (r = −0.864; ~30% amplitude; ~12-day lag), consistent across 25 annual cycles and robust to detrending and bootstrap tests. A 156-event planetary survey yields 72 significant responses, with 34 surviving Bonferroni correction, including enhancement factors up to 955×. Long-period signatures inaccessible in shorter datasets include 18.6-year lunar nodal coupling (R² = 0.640; p < 10⁻⁸) and a semiannual nutation component (R² = 0.902), alongside suggestive Chandler wobble structure (R² = 0.106). A network-synchronization index of 0.582 indicates globally coordinated timing-field behavior. Prior work demonstrated cross-center consistency over 2.5 years (CODE/IGS/ESA, R² = 0.920–0.970). This extended dataset enables decadal-scale tests; continued independent validation, seasonal controls, tidal-predictor modeling, and multi-center long-baseline replication are recommended.
