I'm new to this forum and am a user, not an admin. I've tried to find any reference to this issue in the forums without success. We are using Zimbra version 5.0.18_GA_3011.RHEL5_64 at our university. It appears that when I switch from the month view to the week or day, only the hours between 8:00 a.m. and 5:00 p.m. appear. Likewise, I have created a webpage with an embedded calendar that links to one of my Zimbra calendars. It, too, only displays 8:00 a.m. - 5:00 p.m. In our department, many of our activities take place in the evening, so this is a significant limitation. Is there a setting I haven't discovered that would allow me to adjust this?
