Great, Simple and Effective !

Question 1:
I did install Openntpd to synchronize time. I guess you did'nt invent your own time ?

Suggestion: Trying the alarm tones seems only to work by entering the current time. In the original clock you could hear the sound by changing the option to another tone. I liked that, felt intuative, but don't think it is an important issue.

Thanks , excellent work !
