Use 12 hour format on all cases

[João Pedro Serra]

For me it's kind of inconsistent to have toStringreturning a 24h format and getNextreturning 12h format. I think it would be better to stick with only the more universal AM/PM format.

+1 on consistency
-1 on defaulting to AM/PM

@pekeler true, at the time and because of personal need, I came up with this for consistency sake, but better approach would be to make it configurable
