Dozenal Clock

A dozenal (duodecimal, or base-twelve) clock and homescreen/lockscreen widget. Uses "X" for "ten" and "E" for "eleven." The app itself is full-screen and keeps time in four-digit Tims (that's 1x10^-4 hours), with the Tims separated from the whole hours by a semicolon (";"). The widget keeps time in two-digit Tims (that is, the two largest Tims), with the Tims separated from the whole hours by a semicolon (";"). The widget also display the date. The app updates automatically when open; the widget, in order to preserve battery life, updates only when the time is tapped by the user.
