My #1 suggestion is to have system time be GMT, and every shell/user set TZ appropriately. That's basically the only sane setting, as many time zones do DST (and change the rules for it from time to time). Otherwise, you'll have to provide TZ to cron, presumably in /etc/default/cron or similar... but that will also cause problems if anyone else assumes that cron is in a different timezone. -- Don Armstrong http://www.donarmstrong.com Who is thinking this?
