[LinuxPPS] Strange offset behavior

Not unless it was included in LinuxPPS 2.2.0. (I know, I know.)

I did not change anything specifically in the NTP build, so unless it
was set by default in ntp-4.2.3p12, no.

I'm not sure. How do I find out?

2.6.17.6, unfortunately, in Fedora Core 5. If this convergence patch
really has such a great effect, then I will make it a priority to update
these old systems.

However, both systems are running the same kernel and NTP versions with
the same builds and patches. Why would one system show so much more
consistency?
