Description

When you have changed the BIG-IP system timezone, the cron daemon may not update the effective change of date and time to the existing cron jobs.

This issue occurs when all of the following conditions are met:

  • There were cron jobs configured in the BIG-IP system.
  • The BIG-IP system timezone was changed, with at least a difference of one hour.

A scheduled cron job will run at the date and time that is based on the previous timezone, and not based on the updated timezone.

Symptoms

As a result of this issue, you may encounter the following symptoms:

  • The cron jobs that you expected to run at the date or time that is based on the newly-updated timezone did not occur.
