Int the calendar view that comes up when I click on the digital clock, there are two arrows on either side of the 'Today' button. Clicking on these buttons, moves the date by 3 instead of 1.
For example, while in 'Days' mode, these buttons are supposed to move the calendar by one month (their tooltips say that too). But they move by 3 months instead. If it is showing the calendar for June, clicking next shows September instead of July.
In 'months' mode, it moves by three years instead of one. In 'years' mode, it moves by three decades instead of one.
