How to read
A binary coded decimal can be read with each column added up with each light worth (from top to bottom) 8, 4, 2, and 1, and the column on the left being worth 40, 20, and 10. This is done with each set, which (from left to right) are for hours, minutes, and seconds. For example, the clock to the right shows a time of 4 hours, 22 minutes, and 37 seconds.
