i want to create custom time slot in kendo day scheduler. For example i want to create the time slot of 15 min duration from 9:00 am to 1:00 pm and after that i want to create time slot of 30 minutes duration from 1:00 pm to 5:00 pm. i am getting time slots from DB and i want to create slots as it is as its coming from DB.how can i Override the default slot creation functionality of kendo calendar.By defining "majorTick" i am getting all slots with same time duration but i want to customize this duration according to the time coming from DB with each row. Any suggestion/idea to achieve this functionality.
