My report has a parameter _REPORT_DAY (java.util,Date) and an expression like DAYS(TODAY(), $P{_REPORT_DAY}) The days-diffence function DAYS() seems to consider the time-parts of a day as well: now_REPORT_DAYDAYS(TODAY(), $P{_REPORT_DAY}) =18.07.14 17:16:0019.07.14 17:13:00018.07.14 17:16:0019.07.14 17:17:001 How do I check if _REPORT_DAY is tomorrow, irrespective of the time of the day?
