Dealing with time is a fundamental feature of the human experience, both objective, or so-called clock time, and subjective, personal constructions of time. The focus of this chapter is the construct of time perspective (TP), which is viewed as an integral part of the subjective or personal experience of "lived time". Time perspective is considered to have cognitive, emotional, and social components. The Zimbardo Time Perspective Inventory (ZTPI) is the latest modification of the STPI, which has addressed the shortcomings of the previous scales. Zimbardo and Boyd demonstrate that both Past-Negative and Present-Fatalistic perspectives are associated with strong feelings of depression, anxiety, anger, and aggression. Despite being conceived primarily at a theoretical level, the constructs of TP and a balanced TP offer considerable potential for practical interventions in clinical and occupational psychology. The construct of TP has a potential to provide a theoretical underpinning for time management interventions.
