When generating the report all events that occurred on a given day are taken into consideration. It means that events that occurred at the turn of the day are divided and attributed to a given date. E.g. if a disk or a day from a driver’s card is from 05.12.2002 and contains an event (drive, work, availability) starting before midnight and ending after midnight, it will be divided into two events. The first one ends at 23:59 and the next one begins at 0:00 and lasts till the end of the initial event. The second part of the event is attributed to the next day, i.e. 06.12.2002.
