Change the time that AA starts at Night for Partner Messaging Hunt Group Time Schedule??

Customer has Partner system.. My notes say Partner Messaging.
I know he has sub menus. I need to change the Hunt group time schedule, I think.
I know VM has outcalling abilities if this helps.

I do not see anything in my Partner Mail or Partner Mail VS cheat sheets.
Can someone please explain for all types of Partner Voice mails how to go in and change auto attendant start and stop times?

Thank you.
