BUG: TimeScale in Calendar DayView is incorrect

There seems to be a bug in the TimeScale of the Calendar control in DayView.

The picture below is the Calendar sample from CJ samples.
The picture shows the changes in code that I have made to the sample;

CalendarControl.DayView.TimeScale = 45
CalendarControl.DayView.TimeScaleMinTime = #9:00:00 AM#
CalendarControl.DayView.TimeScaleMaxTime = #6:00:00 PM#
CalendarControl.Options.WorkDayStartTime = #9:00:00 AM#
CalendarControl.Options.WorkDayEndTime = #6:00:00 PM#

When you run the sample in DayView and if you KeyDown with the keyboard from the top of the DayView cell (9:00 AM) to the Bottom, you will see in the immediate window the date entries are correct for a TIMESCALE INTERVAL of 45 minutes.

BUT, the Calendar Control is displaying the wrong TimeScale Caption entries on the left of the control.

If you double-click the last cell in the DayView, you will notice that the Start and End times (5:15PM to 6:00PM) are correct in the Calendar Event window.

CJ, can you please verify if this is a bug or just a constraint that we have to live with, that being non-standard TimeScales (eg 45 mins.)

The TimeScale works if it is set to 6,10,20,90,120 etc..!
It seems to work if it is a multiple of 60.
