[Clock app] Tweak behavior of timer second hand

This bug can be best described with an example,

To set a timer for 01:30 (mm:ss), currently this can be done by clicking on the second label followed by adjusting the second timer hand to 30. Then click on the minutes label and set the minutes timer hand to 1.

However according to design, this has to be done by clicking on the seconds timer hand and rotating it one and a half cycle to set 01:30. This needs to be implemented.

Pros:
- Easy setting of small timers
- No awkward setting of 1 min or 2 min where the angle is too small to be done on a small touch screen.
