Which cron syntax does this builder use?

The standard five-field format: minute, hour, day of month, month and day of week — the syntax used by crontab and most schedulers.

In which timezone are the next run times shown?

In your browser's local timezone. Servers often run cron in UTC, so check your scheduler's timezone before relying on the preview.

No. Six- and seven-field variants (Quartz, some cloud schedulers) are not standard cron; drop the extra fields when copying between systems.
