User cannot login from from 12am - 9am , the settings will be: * * 0-9 * * ?

note that you can add more than 1 settings, and it will be combined by the system. For Example : 

User Cannot login from 11.30pm - 11.59pm and 12am - 9am. the settings will be : 

* 30-59 23 * * ?

* * 0-9 * * ?

for each settings, you need to enter new line, so if you have 2 settings, you will have 2 lines of settings

 * 30-59 23 * * ?
