Not at the station in which I can access all of the code I have, however I can tell that you're not using the same format as all of the other attributes.
'desc'=>'Time System','title'=>'Time System','href'=>'https://mysite.com/timetracker'
If you see above, they are encasing the attribute in single quotes, and using the => sign to determine the value. Commas are also used to denote another attribute.
You can try updating the code to follow it, but since this is using the function addSubMenu, I'm not even certain that it will be allowed in the call. You may need to modify addSubMenu to allow for it.
