Time Now Layer
The time now layer draws a vertical line at the location of the 'time now', which is usually the current system time. However, a Gantt chart can choose to have its own current time. The Gantt chart can choose whether it wants to display the time now or not. An autoscroll feature is also available, which will ensure that the time now cursor (vertical line) will always stay within the visible area, which causes an automatic scrolling of the timeline.
