Change Timezone H2N 4

Hi, I'm encountering a problem regarding the timezone because if I activate the "today" filter in my reports I notice that the day starts at 1am and not at midnight...the times between the hands recorded on hand2note and played on pokerstars coincide. ..so changing the option in Configuration -> Rooms -> Pokerstars -> Time zone shift (hours) is not for me.. is there a way to set midnight as the default starting time of the day?
Sorry for my English it's not my native language
