/**
* Represent a duration in seconds as a string

* @param {number|string} value - A finite number, or its string representation

* @example
* var mf = new MessageFormat();
*
* mf.compile('It has been {D, duration}')({ D: 123 })

*
* mf.compile('Countdown: {D, duration}')({ D: -151200.42 })
* // 'Countdown: -42:00:00.420'
