how to costumize the hours-bar in Calender?

If I configure CellDuration=15 and CellsPerHour=4, i will get 4 lines that splits up 1 hour. In the default view I can just see one full hour. I wan't to add the minute values to each line.

Example for 11 o'clock

11:00________________________________

11:15________________________________

11:30________________________________

11:45________________________________

Thil will make it easier to read the calender especially when the cellDuration is small (5 minutes for example)

Is it possible to configure that? How can I do that?

Thanks for your help
