Check the following configuration: https://blazorrepl.telerik.com/cHvuPOYX27peykXr18 ( SlotDuration="720"  SlotDivisions="1").

The start time of the appointment is 12:00 PM today. The Scheduler, however, displays the start at 12:00 AM on the next day even though the arrow indicates the event continues from the previous day.

For reference, if I set SlotDivisions="2", I get the expected result: https://blazorrepl.telerik.com/GxFOvYED302CzPCo32.
