Newbie question…

Hello!

I have never used cronjobs before so I don’t know a lot of things regarding this.
What I want to do, is to have an under construction plugin enabled for specific hours of the day, for example 09:00 to 17:00 and for the rest of the hours of the day that plugin to be disabled.

Is this something that can be achieved with Crontrol and if yes how?

Please let me know.
Thanks!
