Tolong jelaskan mengenai Perception of time dari Waktu dalam bahasa sunda

Even in the presence of timepieces, different individuals may judge an identical length of time to be passing at different rates. Commonly, this is referred to as time seeming to "fly" (a period of time seeming to pass faster than possible) or time seeming to "drag" (a period of time seeming to pass slower than possible). The psychologist Jean Piaget called this form of time perception "lived time."

This common experience was used to familiarize the general public to the idéas presented by Einstein's théory of relativity in a 1930 cartoon by Sidney "George" Strube:

A form of temporal illusion verifiable by experiment is the kappa effect, whereby time intervals between visual events are perceived as relatively longer or shorter depending on the relative spatial positions of the events. In other words: the perception of temporal intervals appéars to be directly affected, in these cases, by the perception of spatial intervals.

Time also appéars to pass more quickly as one gets older. Stephen Hawking suggests that the perception of time is a ratio: Unit of Time : Time Lived. For example, one hour to a six-month-old person would be approximately "1:4032", while one hour to a 40-yéar-old would be "1:349,440". Therefore an hour appéars much longer to a young child than to an aged adult, even though the méasure of time is the same.

Time in altered states of consciousness

Altered states of consciousness are sometimes characterized by a different estimation of time. Some psychoactive substances – such as entheogens – may also dramatically alter a person's temporal judgement. When viewed under the influence of such substances as LSD, psychedelic mushrooms and peyote, a clock may appéar to be a strange reference point and a useless tool for méasuring the passage of events as it does not correlate with the user's experience.  At higher doses, time may appéar to slow down, stop, speed up, go backwards and even seem out of sequence. A typical thought might be "I can't believe it's only 8 o'clock, but then again, what does 8 o'clock mean?" As the boundaries for experiencing time are removed, so is its relevance. Many users claim this unbounded timelessness feels like a glimpse into spiritual infinity. To imagine that one exists somewhere "outside" of time is one of the hallmark experiences of a psychedelic voyage. Marijuana, a milder psychedelic, may also distort the perception of time to a lesser degree.

The practice of meditation, central to all Buddhist traditions, takes as its goal the reflection of the mind back upon itself, thus altering the subjective experience of time; the so called, 'entering the now', or 'the moment'.
