//时间、时间戳加减 以加一天举例,聪明的你肯定触类旁通
//加一天的时间戳:
var tomorrow_timetamp = timestamp + 24 * 60 * 60;
//加一天的时间:
var n_to = tomorrow_timetamp * 1000;
var tomorrow_date = new Date(n_to);
//加一天后的年份
var Y_tomorrow = tomorrow_date.getFullYear();
//加一天后的月份
var M_tomorrow = (tomorrow_date.getMonth() + 1 < 10 ? '0' + (tomorrow_date.getMonth() + 1) : tomorrow_date.getMonth() + 1);
//加一天后的日期
var D_tomorrow = tomorrow_date.getDate() < 10 ? '0' + tomorrow_date.getDate() : tomorrow_date.getDate();
//加一天后的时刻
var h_tomorrow = tomorrow_date.getHours();
//加一天后的分钟
var m_tomorrow = tomorrow_date.getMinutes();
//加一天后的秒数
var s_tomorrow = tomorrow_date.getSeconds();
