Hi Paul, I'm sorry but that's not right. In the system time is more than 2 "away" from the result that sntpclock fetches you will get the error: "sntpclock: fatal: time uncertainty too large" Please see this example: (current date) # date Tue Nov 12 19:17:16 CET 2002 (verify that sntpclock works) # sntpclock 192.38.7.240 | clockview before: 2002-11-12 19:17:34.487208000000000000 after: 2002-11-12 19:17:34.482176999902330338 (then change the date) # date 111019102002 Sun Nov 10 19:10:00 CET 2002 (and run sntpclock again) # sntpclock 192.38.7.240 | clockview sntpclock: fatal: time uncertainty too large clockview: fatal: data split across packets (then change the date so that is it within the 2 days interval - current time is now 19:18:50) # date 111019202002 Sun Nov 10 19:20:00 CET 2002 (and run sntpclock again) # sntpclock 192.38.7.240 | clockview before: 2002-11-10 19:20:02.052874000000000000 after: 2002-11-12 19:19:58.966644499913759529 kind regards Uffe ----- Original Message ----- From: "Paul Jarc" <[email protected]> To: <[email protected]> Sent: Tuesday, November 12, 2002 7:09 PM Subject: Re: sntpclock: warning: unable to read clock: timed out > "Uffe Jakobsen" <[email protected]> wrote: > > If your local clock differs from the sntpclock result by more than 2 days > > sntpclock will fail > > Propably with the mesg: "sntpclock: fatal: time uncertainty too large".... > > No, that message means your network is too slow, so sntpclock can't > pin down the difference between the local and remote clocks with > enough precision. > > > paul >
