7. T+00:00:00 [note]

A faint nudge at thirty minutes became a definite threshold at one hour, a plus-one by ninety minutes, and an unmistakable plus-three by about three hours, possibly still rising. There was no bodily discomfort or push at all, and the writer mused that a first-timer might find such intensity frightening even though experienced users no longer lose their center at this level. Around hour three there was mild loosening of time-sense — more a laziness about tracking the clock than true distortion — with equal appeal in writing and eroticism, in a good-humored, serene frame of mind.
