Minutes are indicated by causing an element to produce another kind of optical output such as intensity modulated illumination. The particular element selected for intensity modulation is a coarse indication of minutes (5 minute increments); the modulation itself is a fine indication of minutes (1 minute increments). Similar techniques may be employed for indicating the month and day.
