cron jobs change time after DST

My cron job is running an hour later after end of DST. This didn't happen to other user's jobs on the same machine (AIX). What am I doing wrong?

From stackoverflow

• You have probably already checked this, but was the time changed correctly on the server?

  David Nehme : yes, the time changed on the server. The run-time of my job is changed relative to the server.

  Darryl Hein : So, you're saying the time of the cron jobs changed to 1 hour later when the time changed?

• If you are converting UTC into local time(correctly) and the job is for a non-DST timezone, like Arizona, it will run an hour later, relative to your server.

• I think the first thing to find out is the timezone that cron is running under:

  0 1 * * * (/usr/bin/date ; /usr/bin/date -u) > ~/cron.out

  You might also want to get one of the users whose cron jobs are working to do it as well.
