Cześć.
Mam problem z budzikiem.
Problem polega na tym, że po ustawieniu godziny w której powinien zacząć dzwonić nie dzieje się totalnie nic.

Czy jest ktoś w stanie napisać mi co jest nie tak i jak to poprawić?

Ale pytasz konkretnie o to czemu nie działa czy tak ogólnie co jest nie tak? Bo mało co w tym kodzie do czegokolwiek się nadaje. Komentarze z d**y, wykomentowane linie, god-object pattern (ten twój ClockAlarm to jest one class to rule them all ewidentnie), generalnie kod jest do zaorania.
A czemu alarm nie działa? Zapnij się debugerem w metodzie run i zobacz co się dzieje...
