Which one is the actual state? If both this day and the actual daytime are in an entry then this entry is active and the entries state is returned. In case there are more than one active entries the 'hardest' is dominant ( disabled < suspended < enabled ) 2. When will this state end? For all active entries we compute the end of the range. For all inactive entries we compute the start of the range. We iterate through all these ranges beginning with that range which is closest to 'now' in the future. In some cases the state does not change but the range which is responsible for that state changes: mon-fri=9-18 fri=18-19 CALENDAR year CA_yday_range_list TMR_begin TM_mday TM_mon TM_year TMR_end TM_mday TM_mon TM_year CA_daytime_range_list TMR_begin TM_hour TM_min TM_sec TMR_end TM_hour TM_min TM_sec CA_state week CA_wday_range_list TMR_begin TM_wday TMR_end TM_wday CA_daytime_range_list TMR_begin TM_hour TM_min TM_sec TMR_end TM_hour TM_min TM_sec CA_state FUTURE ENHANCEMENTS The compution of 'next_event' could be improved.
