## Warnings

### Interpreted in UTC (info)

A cron expression has no timezone of its own — the scheduler's zone decides when it fires. These times are computed in UTC. The same expression on a host in another zone runs at a different moment.

**Fix:** Set the schedule timezone explicitly (TZ= or CRON_TZ= in crontab, `timeZone` in Kubernetes, or the scheduler's own setting). Vercel Cron Jobs always run in UTC.
