Hope there will be a fix for it someday. Isn't it so that cron is aware of daylight savings time changes, and will not run the same cronjob twice if on a given day hour x occurs twice? Or can be configured to be aware of that? An alternative I'm using at the moment is to have root be in UTC. Downside is that your snapshot names will be in UTC time. Just thinking outloud, didn't give it lots of thought. Marco -- Success is having to worry about every damn thing in the world, except money. - Johnny Cash
