ClockFu's default behaviour appears to be to 'turn off' the day/night indicator, on the Minimap, which is now the new Calendar.  Although it is possible to re-enable the calendar it often goes missing after reloading the UI.  It might be better to remove this functionality altogether, and allow Minimap addons to manipulate the new calendar, if this enabling cannot be stabilized.  I can see the logic, pre-patch, of enabling/disabling the time indicator in a clock addon.  However, post patch, it becomes a more tenuous extension to ClockFu.

Leave it out entirely.  All we really want is a tiny clock on FuBar that displays either server or local time...or both.

To fix the day/night indicator(calendar) option, after line 102 in ClockFu.lua before the line that says end, add these 3 lines of code:
    else
        self.db.profile.bubble = false
        self:ToggleShowingBubble()
