Ladybu time schedule

Hello
I am simulating the behaviour of different adaptive solution to be implemented at building level. The idea is to compare their effectiveness to confront heat waves, so, the period will be defined according with heat wave event. The simulation are carried in Spain, due to the time change we have, I would like to know with time schedule use ladybug, winters one or summers. Depending on what it uses I may have to modify the hour of the result (+1 hour or – 1 hour)

Thanks
Estibaliz
