- * @module rspamd_task
- * This module provides routines for tasks manipulation in rspamd. Tasks usually

- * and add the corresponding symbols to the scan's results.
- @example
- rspamd_config.DATE_IN_PAST = function(task)
- local dm = task:get_date{format = 'message', gmt = true}
- local dt = task:get_date{format = 'connect', gmt = true}
- -- A day
