Spring's @Scheduled(cron = "…") takes
six fields — it starts with seconds. Copying a 5-field crontab line
straight into Spring shifts every field by one, which is a classic production surprise. Use the
6-field toggle for Spring and Quartz.
Next-run times are computed in your browser's timezone. A server usually runs in UTC, so verify against the server clock before relying on them.
