Analog clocks has many benefits over digital clock (See: http://chronicle.com/blogs/brainstorm/is-the-analog-clock-out-of-time/6171)
"The analog clock carries certain advantages over the digital clock. First, once learned — once turned into an easy habit — reading and comprehending the meaning of the hands occurs almost immediately. Pilots, for example, like clocks with hands on faces. (When a hand moves suddenly to the left, it means, “Uh oh, the plane is going down.”) Second, reading an analog clock creates a spatial plan of time in the mind. If the hands say it’s 8 o’clock, and it’s the morning, you can “feel” — holistically — how much longer you have until noon. Third, analog time is more fluid and uncertain. Telling time becomes an activity of estimating, rather than locating. Finally, analog clocks permit and even encourage the subjective experience of time. (Of course, to experience time in a completely subjective way, we’d need to destroy all forms of clocks.)"
Unfortunately it is very hard to read time from Ubuntu Clock App's analog display.
"Easy to read time" feature is very important and it should be considered in design process.
To solve this situation, I would like propose adding Analog Clock Markers.
After that implementation, whole application will be consist (every time page, will have Analog Clock Markers), and analog timers will be easy to read.
