A linear clock and method of indicating the time includes twelve linearly arranged regions wherein each region includes an indicator termed a marker, which is capable of representing a unique hour with a twelve hour cycle or a block of time equal to a five minute increment. Interspersed with the twelve linearly arranged regions is a group of four indicators that are capable of representing a one-minute increment and collectively, up to four minutes.

An apparatus may include a display for visually representing solar time and civil time simultaneously. In some embodiments, the apparatus includes a representation of a horizon extending across the display, an icon of the sun corresponding to a solar time by its position relative to the representation of the horizon and to a top portion of the display, the icon of the sun configured to revolve once per solar day about a center portion of the display, and a plurality of hour indications corresponding to civil-time hours of a day, the plurality of hour indications set circumferentially around the display. The angular position of the plurality of hour indications may be rotatable, thereby enabling the civil time of solar noon to appear at the top portion of the display.
