Real time information is Information that is accurate a the time it is produced, but when viewed at a later date it may then be incorrect particularly if the information itself is based upon an event. If the event for example as already taken place then the real time information will then be entirely irrelevant. Such procedures that involve real time include purchasing and reserving tickets for proceedings such as the cinema or train/bus tickets. These tickets will then remain valid until the end of the screening/journey and from then on after they will have expired. Journeys can also be planned using real time as up to date information is readily available on there whereabouts of your travel service, ie bus or live traffic updates for your precise route. There are also realtime flight planners available , which show the exact route and position of an airplane, with details of their departure and arrival times. A more common example of realtime would be webcam, something that in this generation almost any one owns or has the potential to own on.
