A reading of the SNTP documentation (in the .html directory) seems to
suggest that the maximum allowable offset is 60 seconds. The fact that
it asks you for permission to make the change and then ignores your
reply suggests that there is a bug in the version you are using.
Why is your clock set to "Fri Dec 31 19:20:19 EST 1999"? Deprecated or
not, ntpdate could hardly do worse than that!!!!!
