I have question.
How can change time zone on MFE, but MFE is managed by Control Center. I found where I could change NTP but that's it. It's on Policy/Firewall Settings/Server and Service Settings.
So, you don't have access to Control Center or what?)
Anyway, if you can open MFE console you can change time zone:
(On left part of console) Firewalls--> Maintenance-->Date and Time there you can find all you need
