Ok, How is't possible that these three peer servers share time information among themselves ?
For example: Server "A" shall retrieve time information (for example "TI-1") from public server of stratum 1 (ntp1.ien.it), Server "B" shall retrieve time information (for example "TI-2") from public server of stratum 1 (ntp2.fau.de), Server "C" shall retrieve time information (for example "TI-3") from public server of stratum 1 (ptbtime1.ptb.de), TI-1, TI-2, TI-3 are three time information which are many similar but they can't being the same time(for few milliseconds), so "two of them" must align with the other in order to share time information, I think. What's logic to select the server (among these 3 peers) which gives reliable time to two others ?

They share time information among themselves and any one of them can serve time to clients. > _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
