btw, while checking results of nightly DST change I re-sync-ed one of my boxes to ntp server with rdate and got

1099 seconds is ~18 minutes
How much is too much for dovecot?
More than 5 seconds and Dovecot kills itself. <=5 seconds and Dovecot logs a warning and sleeps until it's back in present.
Do you think using -a on rdate would not cause such effect?
fyi rdate(8): -a Use the adjtime(2) call to gradually skew the local time to the remote time rather than just hopping.
It wouldn't, but it would probably take quite a long time.
Why don't you just run ntpd to keep the time correct all the time?
