Calendar Dashlet Auto-Refresh

Hey folks,

Could somebody tell me if it’s possible to auto-refresh the calendar dashlet as well as the other dahslets do, and how it could be done? I see the auto-refesh time option in other dashlets but not in calendar. I need to have calls and meetings in the calendars dashlet when they are created without refresh the home page manually.
I also see this messages from httpd_error

I’m not sure if it’s normal or not, the calendar works for the rest of things.
