63 | * Keep the Time_Span is sync with on the fly addition and removal of traces |
64 | * in a trace set. It must be called each time a trace is added/removed from |
65 | * the traceset. It could be more efficient to call it only once a bunch |
66 | * of traces are loaded, but the calculation is not long, so it's not |
67 | * critical. |
