Time is one of several quantities upon which information systems rely.
The optimization of information gathering, mapping, organizing, and monitoring are time-dependent.
When clocks in an information system are of poor quality, much of the information capacity of the system must be used to keep the clocks synchronized.
For instance, a television signal contains time information as well as visual information. A small percentage of the information capacity of a television signal is used for stabilizing each image in time, synchronizing camera signals with screen signals.
Music, theatre, dance, film, video, performance art, kinetic art, and spoken languages are time-dependent, and rely on a high ratio of signal to noise resolution.
The forms of all languages encode information which is transmitted to the observer over time. In general, information flows from a source through a channel to a receiver, and is recorded and processed in various ways, and at different time rates, which can affect the way in which information is modified.
