To set required time you need just only few seconds and one click!!! One click means PRESS and RELEASE.
It is simple as 2x2....
By PRESSing (touching the display) you set the HOURS, by RELEASing (removing the finger) you set the MINUTES. To make it clear, please, do it as dragndrop gesture.
What about A.M. or P.M.?
To set A.M. touch the outer bound of clock, to set P.M. touch the inner bound of clock.
And the last one. Just for fun.
Right and left pan movement change the background of the clock.
Enjoy!
