There is a distinction between the chronological time of the clock and there is the psychological time of our skiing experiences. In the former, the duration remains constant, second after second. In psychological time, the duration varies, being of a different intensity.
We use chronological time for practical purposes, such as knowing how long it will take to go down a slope or planning when we are going for lunch. On the other hand, psychological time represents our internal experience of time as an experience of flow, duration or when we calculate certain lapses in order to act.
Experience is a measure of real time: a few minutes on the clock can quickly become an eternity when waiting in line to access a lift following a heavy snowfall; similarly, a long day of enjoyable skiing can be experienced in a few hours. Henri Bergson described duration as an experience wherein seconds last for hours and hours may pass like minutes.
