changing timezone affects cron time

Question

I have set up a cron to run at every 26th minute.

$ crontab -l
26 * * * * date > /home/time.txt 2> /home/time_err.txt

The current time shown by date command.

$ date
Thu Aug 25 23:26:00 CDT 2011

The cron runs as expected but when I add the hour field to the cron, it does not work.

42 23 * * * date > /home/time.txt 2> /home/time_err.txt

Recently the system Admin changed the timezone of this server to CDT from EST. Is the cron problem because of that? How do I correct this?

What does 'not work' mean? The datetime in time.txt is wrong? — quanta, Aug 26, 2011 at 4:54
Did you take a look at /var/log/cron to make sure that cron is not running? — quanta, Aug 26, 2011 at 5:15
Thanks. looking at the cron it was clear that the cron DID run. User cron could not overwrite a file created by root cron. — shantanuo, Aug 26, 2011 at 6:41
