时间戳的相互转化

//hope_time的格式是09:34分
var hope_time = $('#time-options').val();
var myDate = new Date();
var year = myDate.getFullYear();
var month = myDate.getMonth() + 1;
var day = myDate.getDate();
if (month < 10) month = "0" + month;
if (date < 10) date = "0" + date;
//转化为年月日时分秒，秒数填0
var date = ""+year+"-"+month+"-"+day+" "+hope_time+":00";  
//将该时间段时间转化为时间戳
var timestamp2 = Date.parse(new Date(date));
//转化为毫秒
timestamp2 = timestamp2 / 1000;

//时间戳转化为年月日时分秒格式
function getDate(uData){ 
    var myDate = new Date(uData*1000);
    var year = myDate.getFullYear();
    var month = myDate.getMonth() + 1;
    var day = myDate.getDate();
    var hours = myDate.getHours();
    var minutes = myDate.getMinutes();
    var second = myDate.getSeconds();
    return year + '-' + month + '-' + day +'   '+ hours + ':' + minutes + ':' + second;
