	return val + plural;
}

function secondsToString(seconds) {
	var time = Math.round(seconds / 60);

	if (time >= (60 * 24)) {
		var days = Math.floor(time / (24 * 60));
		var remaining = Math.floor(time % (24 * 60));
		return this.formatPlural(days, 'day', 'days') + ', ' + this.minutesToString(remaining);
	} else if (time >= 60) {
		var hours = Math.floor(time / 60);
		var minutes = time % 60;
		return this.formatPlural(hours, 'hr', 'hrs') + ', ' + this.minutesToString(minutes);
	} else {
		return this.formatPlural(time, 'min', 'min');
