Change into winter and summer time

When we enter into summer time the clock has to be adjusted forward one hour during the night between Saturday and Sunday from 3 a.m. to 4 a.m. When we enter into winter time the clock has to be adjusted backwards one hour during the night between Saturday and Sunday from 4 a.m. to 3 a.m.
This might as well affect the worker's working hours.

In principle, a worker who is on duty the nights in questions will recieve pay, working time allowence and Sunday compensation
according to completed working hours. For a worker with a monthly salary, the working hours will be compensated during the adjustment period and the allowences paid according to the working hours performed.
