OrbisTempusColorem; global times mediated through colour.
Artist: Ken DevineProgramming: Mike Blackman

Time is relative Time is simple; time is complicated. In a globalised world time is organised into time zones, they bear a partial relationship to the position of the sun as the earth rotates on its axis; but this is a partial relationship. World Standard Time Zones are generally arranged in ±1 hour intervals calculated from the 0° prime meridian although it's national governments that decide which time zone they wish to be in. Some create their own divisions within the 1 hour intervals e.g. -4:30hrs, +3:30hrs, +4:30hrs, +5:30hrs, +6:30hrs and +9:30hrs. Some then make adjustment related to spring and autumn; ±1 hrs forward and back. It depends upon what is seen as being most appropriate for their particular circumstances. Many cities on the same longitude therefore are in different time zones; 'what time' is a political decision. Which time zone to join is a strategy to unify a political territory partially determined by position in relation to longitude and the therefore sunrise and sunset, and partially in relation to political geography. Some political entities straddle so far east and west that they have multiple time zones. All times of all days are crushed together at the North and South Poles; it's whatever time of day you want it to be. There is specific month-time and year-time but its relationship with day-time breaks down. E = mc˛. The experience of time is not necessarily dependant on recognition of duration related to the steady counting of intervals. Long or short 'times' have no reliable independent gauge they are wholly contextually based. OrbisTempusColorem time zones relate to UTC/GMT based on world standard time zones and 24bit RGB colour as the medium. Unix time or POSIX time or Epoch time, is the 'time' that is used as a basis. It is the point in time used to calculation the time that has elapsed since or back from, 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970. Daylight Saving is not taken into account. |  | Colour is relative Colour is simple; colour is complicated. The basic visual elements of colour in European/USA models are frequently quoted as: Hue; chromatic colour related to the spectrum of visible light. Saturation; the purity of a hue, in relation to the amount of grey. Tone; the amount of white or black within a hue, sometimes divided into tints; the relative amount of white, and shades; the relative amount of black. Brightness; the amount of light and the distance from the eye. These are qualities related to characteristic of visible light, but the space between origin and reception can be subject to Red to Blue Shift: which is the attenuation or compression that relates to whether the origin of the light is moving relatively away or towards us. This is an expression of relativity and time dilation. E = mc˛. Colours are rarely seen in isolation they are always in contexts. These are not qualities related to the wavelength of light or any particular physical colour system. Material surface qualities e.g.; the smoothness, roughness, lumpiness, spikiness, curviness, wetness, transparency, the Semantics of Colour; the language scheme used for categorising colours, concepts of harmony, association with ideas of ugliness or beauty or other similar associations, metaphorical association, identification with specific objects, identification with emotional states, colour constancy, the effect of after-image, the condition of colour blindness or blindness itself which despite the absence of light can still be associated with a colour experience, the condition known as synaesthesia where colour has a multi-sensory dimension, the Munker-White effect, non-sensory determined colour experience; memory colour, ecologically and environmentally and culturally positioned predispositions.
