  timeZone: "America/New_York"

          containers:
            - name: job
              image: busybox

    Spring @Scheduled

    // Spring has an extra seconds field first
@Scheduled(cron = "0 */30 9-18 * * 1-5")
public void run() { /* ... */ }

    Note: cron runs in the time zone of the machine or platform. Servers and GitHub Actions usually use UTC; Kubernetes lets you set timeZone.
