[Expert] Time zone change confuses cron

Paris,
18 Feb 2008,

Dear all,

We receive a highly anormal volume of connexions from agregated nodes,
or unknown IP's. That organization is particulary unclear to me :

Having a problem to generate trace files.

Ever had a Crontab that does not obey the Unix Time Zone ?

Unix/Fedora core 2/Apache/2.0.50 (Fedora) for pc-linux-gnu on i686
mysqladmin Ver 8.23 Distrib 3.23.58,

Date (ssh command : date) is : Mon Feb 18 18:43:17 CET 2008

BUT in crontab events :

34 23 * * * run-parts [Volume 1]
3 3 * * 5 run-parts [Volume 2]
33 02 * * * run-parts [Volume 3]
55 * * * * sh /etc/cron-scri/backmaker [Volume 4]
*/5 * * * * sh /etc/cron-scri/restoresql2 [Volume 5]

Events are not respecting the Unix time !

As an example :
* */3 * * * run-parts [Volume 10]
That script should be run every 3 HOURS, whatever the Time Zone is.

On another server set on the default Miami time, everything was runing
fine. But set up in the Western-Europe time that script is runing
every minute.

Do you know how to get the CRONTAB respecting the UNIX time ?

Many thanks for any advices from your knowledge and experience.

No! It will run every minute of every third hour. Specify a minute if
you want it to run once every three hours.

Is there any problem with the other crontab lines?
