+- It appears AWS's wildcard support borrows heavily from Quartz Job Scheduler cron expressions. More documentation about wildcard handling than AWS provides is available in the [Cron Trigger Tutorial](http://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/crontrigger.html). _NB: AWS doesn't support seconds (i.e. AWS has 6 fields, while Quartz has 7), so ignore the first field in the Quartz documenation._
