In Logic Pro, do one of the following:
Open the Project Settings > General pane, then click “Project Type: Use musical grid” to show the time format in bars and beats. Click the checkbox a second time to clear it (unchecked), which displays the time format in minutes and seconds.
Choose View > Show Event Position and Length as Time in the Event List. This only applies when “Use musical grid” is active.
