根据unix时间戳返回一个相对当前时间的格式,如:3天前,24秒前等等
//############################### //Usage: var myRelativeTime:String = timestampToRelative("Sun Oct 24 20:07:33 +0000 2010"); //returns a string //############################### function timestampToRelative(timestamp:String):String { //--Parse the timestamp as a Date object--\\ var pastDate:Date = new Date(timestamp); //--Get the current data in the same format--\\ var currentDate:Date = new Date(); //--seconds inbetween the current date and the past date--\\ var secondDiff:Number = (currentDate.getTime() - pastDate.getTime())/1000; //--Return the relative equavalent time--\\ switch (true) { case secondDiff < 60 : return int(secondDiff) + ' seconds ago'; break; case secondDiff < 120 : return 'About a minute ago'; break; case secondDiff < 3600 : return int(secondDiff / 60) + ' minutes ago'; break; case secondDiff < 7200 : return 'About an hour ago'; break; case secondDiff < 86400 : return 'About ' + int(secondDiff / 3600) + ' hours ago'; break; case secondDiff < 172800 : return 'Yesterday'; break; default : return int(secondDiff / 86400) + ' days ago'; break; } }
