Grekeli contact input arrival whether to start counting down began. I watched the beginning, wait. Remaining: 23:13 '23:12 after ten, but was 23:73. In an odd situation. Added a full 60 minutes. Then started counting upwards. After a while, began to count down again. "ANY" can also add hours and minutes, seconds him? (HH: MM: SS)
