Current Time Indicator
Documentation
This example shows how to enable the current time indication. The switches under the Scheduler allow you to specify how to indicate the current time: by using a specific indicator, shading or both of them. You can also specify how often the Scheduler updates their position using the «Update position in» number box under the widget.
Feel free to share demo-related thoughts here.
