I'm not sure about Lenny/xen specific issues but the fact that machines
coming up can have deltas large enough to stop ntpd from adjusting the
clock is not uncommon, and normally you find people run ntpdate in
whatever rc file starts up ntpd so that ntp is able to adjust the time
from then on.

Thanks Nigel. Note - ntpdate is happy to adjust this - but dovecot thinks this is bad and kills itself to prevent problems (http://wiki.dovecot.org/TimeMovedBackwards). 

This large time delta on boot is a big change from Debian Etch. 

I am not running NTP - just ntpdate (cron - set clock once a day). Maybe I shouldn't.

Cheers,
