Returns a Duration representing n seconds. This function takes a number and converts it into a Duration type value, expressed in seconds.
seconds(120) returns a duration of 120 seconds. seconds([100yd Dash Finish Time]) converts the numeric value in the 100yd Dash Finish Time field into a duration expressed in seconds. The number doesn't change, just the data type. [Start Time] + seconds(10) returns the time of day that's 10 seconds after the time of day in the Start Time field.
