Thiis is a 3 time zone clock. You can change the settings by right clicking on the widget. If you do not know how to read any of the aviation clocks you can ask and I will give some instructions but its not really that difficult. For example the heading indicator clock has moving dials instead of hands. The compass dial is the hour dial and is read using the triangle pointer which is located where the North marker should be. The second dial is the minutes and you read them at the center of the nose on the plane pointer and the center orange line is the second hand.
For the Horizon clock (clock in the center) the white tipped hand is the hour hand and the grey and white hand is the minute hand which is read using the white part.
There is also a working power gauge on the climb indicator clock for laptop batteries.
