I was inspired by Magda's seminar this monday about the variability of css, gps or whatever. She said that variability is something like a hundret years. And then I thought: shouldn't it (the period) be corrected for the expansion of the universe since these objects happend to be so strongly redshifted ? Or maeybe this effect is negligible.
