Returns:

Type: number

toSeconds(time, now) → {number}

convert Tone.Time into seconds.

unlike the method which it overrides, this takes into account transporttime and musical notation

Parameters:

Name	Type	Argument	Description
`time`	Tone.Time
`now`	number	<optional>	if passed in, this number will be used for all 'now' relative timings
