crontab

[Patrick Dupre]

Hello,

To have the same shell running twice a week, I am using crond and
anacron if I understand correctly. I have a file in /etc/cron.weekly 
(file.cron)
and I also schedule the same file from crontad -e.
However, it appears that I have the same file command
(/etc/cron.weekly/file.cron) started at 2 slightly different times
  started at Sun Dec 26 03:04:01 GMT 2010
and at:
started at Sun Dec 26 03:00:01 GMT 2010

according to my log files. This is a real problem.

How, can I run a cron file twice a week ?

Thank.
