微信小程序获取当前时间戳、获取当前时间、时间戳加减

//获取当前时间戳  
    var timestamp = Date.parse(new Date());  
    timestamp = timestamp / 1000;  
    console.log("当前时间戳为：" + timestamp);  
  
//获取当前时间  
    var n = timestamp * 1000;  
    var date = new Date(n);  
    //年  
    var Y = date.getFullYear();  
    //月  
    var M = (date.getMonth() + 1 < 10 ? ‘0‘ + (date.getMonth() + 1) : date.getMonth() + 1);  
    //日  
    var D = date.getDate() < 10 ? ‘0‘ + date.getDate() : date.getDate();  
    //时  
    var h = date.getHours();  
    //分  
    var m = date.getMinutes();  
    //秒  
    var s = date.getSeconds();  
    
    console.log("当前时间：" +Y+M+D+h+":"+m+":"+s);  
      
//转换为时间格式字符串  
    console.log(date.toDateString());  
  
    console.log(date.toGMTString());  
  
    console.log(date.toISOString());  
    
    console.log(date.toJSON());  
      
    console.log(date.toLocaleDateString());  
  
    console.log(date.toLocaleString());  
    
    console.log(date.toLocaleTimeString());  
     
    console.log(date.toString());  
     
    console.log(date.toTimeString());  
     
    console.log(date.toUTCString());  
 
//时间、时间戳加减 以加一天举例
    //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();
