Ah, it's funny you should ask: Yesterday afternoon I just synched all of
the clocks. I do have a problem with clock drift, even with xntp. I think
one of the upstream servers is skewed, but i have no choice about that. I
have toyed with the idea of getting my own radio clock and becoming my own
stratum 1 server.
However, that's beyond this maiing list. The irony here is that the most
recent backup is where I got the negative numbers was started 3 hours after
I had synced the clocks. I will keep an eye on the clocks but they may not
be the issue.
Thank you for your swift reply...
