I have set up ACPI wakeup so my laptop wakes up at a certain time each morning. The timezone for this is UTC. I want to set up my crontabs also using UTC so they fit with the wakeup alarm. How do you do it? I've tried editing /etc/default/cron to include: TZ="UTC" but it doesn't work. (I've also tried TZ=UTC and TZ="UTC/GMT") Any ideas?
