One patient in a severe depressive episode describes each hour feeling as though it drags on endlessly, yet when asked directly she correctly states the date, the day of the week, and her current location. A second patient, acutely unwell following a urinary infection, cannot say what day it is, believes he is still at home rather than in hospital, and is unsure how long he has been unwell. Are both of these best understood as a distortion of the experience of time?
