Current Time Indicator

The Scheduler indicates the current time if you enable the showCurrentTimeIndicator property. Use the indicatorUpdateInterval property to specify how frequently the indicator should change its position.

You can also shade the timetable up to the current time. To enable this feature, set the shadeUntilCurrentTime property to true.

In this example, you can use the controls under the Scheduler to change the above mentioned properties at runtime.
