JS时间格式化

       function formatTime(date) {var d = new Date(date),   year = d.getFullYear(),   month = d.getMonth() + 1,   day = d.getDate(),   hour = d.getHours(),   minute = d.getMinutes(),   second = d.getSeconds();        return [year, month, day].map(formatNumber).join('-') + ' ' + [hour, minute, second].map(formatNumber).join(':')}function formatNumber(n) {  n = n.toString()  return n[1] ? n : '0' + n}

date为参数，格式为:2548965466,诸如此类时间格式。
