微信小程序獲取當前時間戳、獲取當前時間、時間戳加減

//獲取當前時間戳  
    var timestamp = Date.parse(new Date());  
    timestamp = timestamp / 1000;  
    console.log("當前時間戳為：" + timestamp);  
  
//獲取當前時間  
    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();  
    //時  
    var h = date.getHours();  
    //分  
    var m = date.getMinutes();  
    //秒  
    var s = date.getSeconds();  
    
    console.log("當前時間：" +Y+M+D+h+":"+m+":"+s);  
      
//轉換為時間格式字符串  
    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());  
 
//時間、時間戳加減 以加一天舉例
    //加一天的時間戳：  
    var tomorrow_timetamp = timestamp + 24 * 60 * 60;  
    //加一天的時間：  
    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();  
    //加一天后的時刻  
    var h_tomorrow = tomorrow_date.getHours();  
    //加一天后的分鍾  
    var m_tomorrow = tomorrow_date.getMinutes();  
    //加一天后的秒數  
    var s_tomorrow = tomorrow_date.getSeconds();
