Time zone change confuses cron

[Ladislav Bodnar]

Hi,

I've just changed the system time zone from local time to UTC by 
copying /usr/share/zoneinfo/Etc/UTC to /etc/localtime. To my dismay, I 
found that crontab (both /etc/crontab and user-level crontab) completely 
ignores the change and continues executing scripts according to the old 
time.

What am I doing wrong?

Thanks a lot for your help :-)
