Firstday issue

Hi gentleman,

i'm facing with an issue that i've no idea how to solve. I discovered on guida.sky.it.ini that @ site first day is changing for many different channel:

_channel A guide is starting from monday ( firstday=1234560).
_Channel B guide is starting from saturday (firstday=6012345). Hope is right...

Is there any way to solve this issue ?

Thanks in advance and Regards
