A method and apparatus for displaying to an observer an analogue representation of time by pointing to first and second locations on a scale which extends around a central point and represents time. The method and apparatus are arranged to display a first line to the observer which extends in a direction from the central point to the first scale location. The method and apparatus are arranged to display a second line to the observer which extends in a direction from the central point to the second scale location. The first and second lines are swept across the scale in the same direction as time elapses at different rates proportional to elapse time measured in different units. When the lines extend in different directions from the central point, an area defined between the first and second lines on one side of the first line is visually distinct from an area defined between the first and second lines on the other side of the first line. |
