Cron library supports timezones but tzdata missing from container

The cron library supports the environment variable TZ for setting a time zone but the local tzdata database is not installed by the Dockerfile. The fall-back behaviour is to silently ignore the TZ and switch to UTC so it is not a breaking change.

Tested locally with Docker tags edge and 1.0.
