How to read: Each column represents one-digit in the HH:MM:SS format. Bulb-values are one, two, four, and eight, and are read from the bottom-up. To convert a column's value, add the values of the lit bulbs. For example, if the far-right column has the bottom and top bulbs lit, the value is nine (i.e. 1 + 8).

When reading time, numbers with an adjacent asterisk are "active".
