i added a crontab entry, which was supposed to start in 2 minutes. I waited and it didn't. Here's the entry:
pimp:/# crontab -l
# m h dom mon dow command
59 23 * * 1 apt-mirror /etc/apt/mirror.list &
The "mirroring" was supposed to launch at 23:59 every Tuesday... It was 23:55 when i finished editing. I then restarted and waited, but no process was launched.
