that have little meaning. With the present (and for what I know also future :-) light speed limit, the fiber light spend around 13ms to go to/from my next internet link (minimum ping).
so the accuracy of the atomic clock have to be modified by the time between it's position and mine. How can one achieve this? May be a GPS knowing the respective position of the satellite and the receiver can make a fix, but on internet? it can only give legal time not the precise time I have here on an unknown position
Actually, that's compensated for in NTP. https://en.wikipedia.org/wiki/Network_time_protocol#Clock_synchronization_al... Also, the GPS satellites have their own atomic clocks, which are synced with the U.S. Navy observatory. They wouldn't be using NTP to do that. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
