Yes, you are right, ntpd -q returns different results on the two machines. However, as I said in the original post, the time on the two machines is the same to within a very small amount., well within the five minute tolerance used by kerberos. So I don't understand why it should matter that the two machines have arrived at the same time by syncing with different servers. >as a way around, set up ONE unit to act as the local master, >and then sync against it, to get 'site coherent' time Could you tell me how to do this, or point me at a document that does?
