In brief: Circadian disorder

Delayed sleep phase syndrome (dsps) is partly a genetic condition that results in the delayed timing of sleep with respect to the signal generated by the endogenous biological clock.
One's habitual schedule of exposure to light and dark can contribute to and maintain dsps. Moving one's wake-up time earlier by increments each day, evening melatonin, or morning bright light can ameliorate dsps.

It is also self inflictated condition in may which takes years to decades to change the sleep phase by going bed late like from 9pm to 10 pm and to 12 mid night and later like 1-3am etc. It starts around the teenager and goes into the adult life . Partly related to work, school and life style also. It is not fully genetic it has lot to do with life style also. One can change back to normal sched

Moving ones wake time up is a very difficult endeavor, it is usual to "walk around the clock" with the patient going to sleep later and later until she or he reaches the desired sleep time. Moving in the normal direction of the clock is the easiest to accomplish but is also the longest of the methods.
