[ntp:questions] Data corruption: little / big endian issue ? overflow ?

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 ?
