As a part of a input validation I was thinking whether this is a really valid cron expression and how it would executed:

0 0/0 * * * ?


Quartz validation returns true

org.quartz.CronExpression.isValidExpression("0 0/0 * * * ?")


So, does this run all the time, never, every hour or every minute...?
