Model predictions of .Their so-called solar clock is like a typical clock, where each roughly 11-year cycle can be described over 12 hours. Extending the analyses ofGough(1981, 1983), we find that these data are statistically consistent with random walk of the cycle phase and exclude clock synchroniza-tion with at high levels of . The regular movement of the Sun through the zodiac signs in 25920 years or some 2160 years per sign, can be regarded as a cosmic clock for the cultural ages. The clock plots as its angular coordinate the analytic phase with time increasing clockwise. Extending the analyses of Gough (1981, 1983), we find that these data are statistically consistent with random walk of the cycle phase and exclude clock synchronization with at high levels of .
