    Radio Clock or Internet GMT - which should I believe?
    From: Zvi Doron
    Date: 2012 Mar 2, 19:00 -0000
    I have been using GMT provided over the Internet (via Wi-Fi) to set my time pieces by for celestial navigation, but when compared to a radio clock (AccTim Galaxias) the two time sources seem to differ, mostly by a second or two but sometimes by up to 5 seconds. Intuitively I would have thought that the radio clock would be the stable and accurate one and that the Internet GMT, delivered to a laptop or to a smartphone via Wi-Fi would suffer short delays and inconsistencies. Any thoughts or experience?
