<P> The use of time is an important issue in understanding human behavior, education, and travel behavior . Time - use research is a developing field of study . The question concerns how time is allocated across a number of activities (such as time spent at home, at work, shopping, etc .). Time use changes with technology, as the television or the Internet created new opportunities to use time in different ways . However, some aspects of time use are relatively stable over long periods of time, such as the amount of time spent traveling to work, which despite major changes in transport, has been observed to be about 20--30 minutes one - way for a large number of cities over a long period . </P> <P> Time management is the organization of tasks or events by first estimating how much time a task requires and when it must be completed, and adjusting events that would interfere with its completion so it is done in the appropriate amount of time . Calendars and day planners are common examples of time management tools . </P> <P> A sequence of events, or series of events, is a sequence of items, facts, events, actions, changes, or procedural steps, arranged in time order (chronological order), often with causality relationships among the items . Because of causality, cause precedes effect, or cause and effect may appear together in a single item, but effect never precedes cause . A sequence of events can be presented in text, tables, charts, or timelines . The description of the items or events may include a timestamp . A sequence of events that includes the time along with place or location information to describe a sequential path may be referred to as a world line . </P> <P> Uses of a sequence of events include stories, historical events (chronology), directions and steps in procedures, and timetables for scheduling activities . A sequence of events may also be used to help describe processes in science, technology, and medicine . A sequence of events may be focused on past events (e.g., stories, history, chronology), on future events that must be in a predetermined order (e.g., plans, schedules, procedures, timetables), or focused on the observation of past events with the expectation that the events will occur in the future (e.g., processes, projections). The use of a sequence of events occurs in fields as diverse as machines (cam timer), documentaries (Seconds From Disaster), law (choice of law), computer simulation (discrete event simulation), and electric power transmission (sequence of events recorder). A specific example of a sequence of events is the timeline of the Fukushima Daiichi nuclear disaster . </P>

The order in which events happen in real time is known as
