      Description

      A Cron Entry of "50 20 * * 5" with an AMQ_SCHEDULED_DELAY of 61000 (61 seconds) started at 2011-03-04 20:48:24. The last "5" in the Cron Entry specifies only Fridays and 2011-03-04 is a Friday. The cron job ran and set "next scheduled time" to be 2011-03-10 20:50:25. 2011-03-11 is a Thursday. The correct "next scheduled time" should be 2011-03-11 20:50:25; it should be Friday.

      In addition, the reason why I set the delay to 61000 was because with the default delay of 0, the job executes twice with a 60 second interval. I will file a separate issue.

      I believe the Cron Entry has a problem with using asterisks. I tried a Cron Entry of "27 19 1-31 1-12 6" which is a Saturday. It ran at 19:27 and then correctly set the "next scheduled time" to be on the next Saturday. This is a temporary workaround.
