Timeline Time Ruler

Time Ruler—This appears along the bottom of the timeline and is independent of the Grid. It serves only as a reference to time and can display time in a number of different formats (for example, SMPTE timecode of HH MM SS FF). 

Right-click the Time Ruler at Beat 1 of Measure 3, represented by 3.1 on the timeline, and, from the context menu, select Key. 

Because of the many different types of media that can be used in ACID, time can be measured in a wide variety of ways. The right half of the time display always shows the measures.beats.milliseconds, as does the ruler at the top of the timeline. The left hand of the time display can be customized to fit your preferences. For example, when creating video projects for broadcast in the United States, you would want to use the NTSC video standard, which is SMPTE Drop (29.97 fps, video). To change the format displayed, right-click the time display or the Time Ruler below the timeline. Then, from the context menu, choose Time at Cursor Format and select the format. If the Time Ruler at the bottom of the timeline is not visible, from the View menu, select Time Ruler. Make sure Show Time Ruler is selected and has a check mark next to it. 

Measures are typically separated by lines in a score. The ruler at the top of the timeline in AQD divides time into measures and thousandths of a second.
