Standard 5-field cron expression: minute hour day-of-month month day-of-week. Supports ranges (1-5), lists (1,3,5), steps (*/15), and wildcards (*).
CRON '0 6 * * *'The CRON clause specifies the firing cadence for the schedule using a standard 5-field cron expression enclosed in single quotes. The five fields are, in order: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-6, where 0 is Sunday). Each field accepts wildcards (*), ranges (1-5), comma-separated lists (1,3,5), and step values (*/15). The cron expression is evaluated against the timezone specified by the TIMEZONE clause, defaulting to UTC when TIMEZONE is omitted. This is the only required clause in a SCHEDULE declaration.
