/**

* @param {?} date
*/
function diffDays (date){
var utcThis = Date.UTC(this.getFullYear(), this.getMonth(), this.getDate(), this.getHours(), this.getMinutes(), this.getSeconds(), this.getMilliseconds());
var utcOther = Date.UTC(date.getFullYear(), date.getMonth(), date.getDate(), date.getHours(), date.getMinutes(), date.getSeconds(), date.getMilliseconds());
return (utcThis - utcOther) / 86400000;
};
I couldn't find any documentation about built-in Date object in jsdoc docs. What is the recommended way of specifying the Date type in params list.
