Hi,
I'm experiencing this behaviour:
Computer 192.168.2.12 is synchronized on 192.168.2.2 which is in turn
synchronized on public ntp servers.
Everything seems right as every machine has selected a system peer but
192.168.2.2 date is ok (Wed, Feb 4 2004) whereas
192.168.2.12 date is ... Fri, Jan 17 1936 !
it seems that reftime most significant bit as been lost somewhere,
reftime is c3cb2c8f.2e666666 for the former and only
43cb2be2.12d4801f for the latter.
Any idea ?
