Notes
  • Linux crontab usually uses 5 fields: minute hour day month weekday.
  • Spring / Quartz commonly uses 6 fields: second minute hour day month weekday.
  • Second-level jobs usually require schedulers like Spring / Quartz that support a seconds field.
  • Different frameworks may interpret weekdays and ? slightly differently. Verify with your actual scheduler before production use.
