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

Oct 28 10:32:48 sas dovecot: Time just moved backwards by 1099 seconds. This 
might cause a lot of problems, so I'll just kill myself now.

1099 seconds is ~18 minutes

How much is too much for dovecot?
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.
