It is an artificial arrangement, done to accommodate social norms.
In the UK, correct astronomic time is in the Winter , when the country is on GMT.
However, in the Summer, without day saving time, the Sun would rise at approximately 3:30 am. and set at about 8:30 pm. This means that half of your sleeping time is daylight ( approx. 4 hours) , and conversely about 3 hours of your social time in the evening is in the dark.
So with day-saving time , 1 hour in the UK, sunrise is about 4:30 am and sunset is about 9:30 pm. This allows for normal work and social time to be wholly in the day-light.
There is also the 'animal' response to light. The human animal is a diurnal animal, and finds it easier to arise in the morning , when there is day light and will go to bed when darkness falls, in the late evening. Couple all this to the fact that, be it Winter or Summer, we go to work/school at 8:00/9:00 am
in the daylight and come home in the daylight.
