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.

Only the Partner Messaging R1 and R7 have a schedule controller. About all that does is change the AA menu prompts from day to night and vice versa- like the night service button only the night service button can change the number of rings also. The Messaging can't.

So Hal I'm unsure of the version but can you explain to me if I have R1 or R7, where do I go in programming to modify schedule controller?
Thank you.

It's in the main AA menu- "schedule options".
