Time Intervals
You create and manage Time Intervals using the Interval Bar (the pale line along the top of each selected Lifeline element). Time Intervals enable you to perform various operations on transitions, such as copy and paste. They also enable you to compress sections of the timeline so that they are not visible.
Each Time Interval displays across all Timeline elements down to the last element on the diagram.
