In 4.0.1 the option to disable/hide the default clock attached to the Minimap frame was removed. This addon simply hides it again, no additional options or settings.
You could also simply hide the Minimap clock by adding this LUA code to another addon (with the downside that you need to re-edit the LUA each time you update that particular addon):
Credit for the code goes to Ailae on the WOWI Boards.
Code:
local f = CreateFrame("Frame", nil, UIParent)
f:RegisterEvent("ADDON_LOADED")
f:SetScript("OnEvent", function(self, event, name)
if name == "Blizzard_TimeManager" then
TimeManagerClockButton:Hide()
TimeManagerClockButton:SetScript("OnShow", function(self)
TimeManagerClockButton:Hide()
end)
end
end)
