Reproduce:
DateTimeItem item = new DateTimeItem();
item.setUse24HourTime(false);
item.setShowPickerTimeItem(true);
item.setType("datetime");

Set the time on any date to 12:## AM (where ## is any minute) and click "Apply". The resulting time appears to be changed to 12:## PM.

The problem does not occur if you set the time on any date to 1:## AM and click "Apply". The resulting time is unaltered and remains 1:## AM.

If you change to item.setUse24HourTime(true) the problem does not occur (however, our users prefer the AM/PM selection and 12 hour clock).
