I cannot give more then 3 stars for being very un-intuitive and quite restrictive.

I went to advanced settings, I wrote hours, minutes and ... You get some -- that you must fill, yet. I thought seconds? no. Maybe just leave it and it will be defaulted to some value? no, you must fill it... After clicking random stuff at keyboard it turned out you can fill it with 'a' for AM or 'p' for PM. Great, but how am I supposed to understand that? It's not how other apps do it, nor how it is expected to work. Also for only 2 options "combo-box" could work more intuitively then input field.

Second problem - why force people to use AM/PM in first place? Wheres switch to not use it? I don't even know what AM and PM 'is' (over-exaggeration, but I really prefer to look up which one is which, whenever I have to use it) I prefer 24h clock.
Also when I wrote 17 and it changed to 5, but didn't made it pm - it's definitely not overlooked, but specifically restricted...

good ideas would be : default hour to AM, if user writes 17, change it to 5 PM. Also by defaulting 3rd field into AM, user will know what is supposed to be here. '--' two dashes don't indicate best on what am I supposed to write here.
