Hi Petr, when logging a QSO at 00:00 UTC there is a slight problem, If the QSO starts at 11:58 UTC then gets logged at 00:02 UTC, CQRlog uses the start time and the end date, so lets say the QSO starts at 11:58 8/6/2015 and ends at 00:02 8/7/2015 the log then set the end qso at 11:58 on 8/7/2015 which is incorrect. CQRlog should use the end time and date for the official logging time. very rare that this happens, because you have to log just at the right time, but the bug is there.. Thanks!
