Cron Rule is not Fired

Hi,
I have this rule:

rule "Invia Valori ogni Minuto" when Time cron "0 * * * * ?" then

end

I’m expect that this rule will be fired every minute, but it is not. What’s wrong?

Isn’t it

* * * * *

for every minute?

If i remeber correct openhab is based on quartz Cron http://www.quartz-scheduler.org/documentation/quartz-2.1.x/tutorials/tutorial-lesson-06. This has an option for Seconds.

I simply removed the rule, restarted OpenHab and re-added the rule and now work.
I don’t know why.
