Time perception, time experience is a strange phenomenon

This experience of working under and without time pressure has become an important issue for me. The experience of time perception. An hour in a massive hurry feels much shorter than an hour without haste.The following quote is from philosopher Hartmut Rosa in his book 'Leven in tijden van versnelling' (something like 'Life in times of acceleration'). 'As we all know, only the time as the clock indicates is precisely and objectively measurable, while the experience of time, "inner duration" of an event, can be equally as subjectively different. Depending on the actions or the circumstances in which we are entangled, half an hour can be incredibly short or just take forever.'
