  • Timezone Convert: Convert a datetime from one timezone to another. When show_all=true, displays the time in 7 common timezones simultaneously (UTC, JST, EST, PST, CET, IST, CST).
  • Parse Cron: Parse a standard 5-field cron expression (minute hour day month weekday). Returns: human-readable description, validation status, next 5 run times. E.g. "*/5 9-17 * * 1-5" → "Every 5 minut
