Problems with CRONTAB on Summer Time

Gustavo Souza Lima — Tue, 13 Nov 2007 08:36:30 GMT

Hi...I am live in Brazil and now We are on Summer Time and my crontab doesn't work well.
If I want to run a job at 05:00 AM I need to set my cron to run at 06:00 AM. Why this happen??? I typed a date command to see the time of the system and it was right.

Can someone help me please???

Hi:

The 'cron' damemon handles Daylight Saving time transitions without incident according to a predescribed set of rules described in the 'cron(1M)' manpages. See there.

If you recently updated your 'tztab' file (perhaps with a patch from the ITRC Patch databaase), but failed to stop and restart the 'cron' daemon, this may be the reason for your problems.

Regards!

Oi Gustavo,

First, check the /etc/default/tz file, it should contain the correct TIMEZONE for Brazil. Correct if necessary then try restarting the cron daemon :

#/sbin/init.d/cron stop

and

#/sbin/init.d/cron start

Boa sorte,
