Я запускаю gpsd 3.18.1 в Ubuntu 16.04 с приемником Maestro A2200-A SirFstarIV - GPS-приемник и сообщает о отрицательном времени -2117800015.00 , которое преобразуется в в субботу 22 ноября 1902 года 10:13:05 .
То же оборудование, но с запущенным gpsd 3.4 в Ubuntu 12.04.04 Я получаю правильные результаты.
Пожалуйста, просмотрите мой вывод ниже и дайте мне знать, что мне не хватает.
