## cron.c

* `cron_match(date text, cron_entry text)` allows you to compare dates against cron entries, whether they match or not

* f.e.:

  * `select cron_match('2000-01-01 00:03:00', '*/3 * * * *');` returns 1

  * `select date from test1 where cron_match(date, '*/9 */10 * * *');` returns

    |date|
