一.js将时间转换成时间戳
1.js获取当前时间戳的方法

var timestamp1 = Date.parse(new Date());
var timestamp2 = (new Date()).valueOf();
var timestamp3 = new Date().getTime();

第一种：获取的时间戳是把毫秒改成000显示，第二种和第三种是获取了当前毫秒的时间戳。

2.js获取制定时间戳的方法

var oldTime = (new Date("2015/06/23 08:00:20")).getTime()/1000;
getTime()返回数值的单位是毫秒。

二.js把时间戳转为为普通日期格式
1.Date toLocaleString方法

function getLocalTime(nS) {
return new Date(parseInt(nS) * 1000).toLocaleString().replace(/:\d{1,2}$/,' ');
}

parseInt() 函数可解析一个字符串，并返回一个整数。

js中时间操作单位是毫秒。

toLocaleString() 方法可根据本地时间把 Date 对象转换为字符串，并返回结果。

replace() 方法用于在字符串中用一些字符替换另一些字符，或替换一个与正则表达式匹配的子串。

replace(/:\d{1,2}$/,' ')验证替换以：开始有一位或二位数字的结束字符串，就是秒；替换为空

显示如下：

所以我们可以利用正则表达式改变我们想要的日期格式。

2.Date 属性方法

function add0(m){return m<10?'0'+m:m }
function format(shijianchuo)
{
//shijianchuo是整数，否则要parseInt转换
var time = new Date(shijianchuo);
var y = time.getFullYear();
var m = time.getMonth()+1;
var d = time.getDate();
var h = time.getHours();
var mm = time.getMinutes();
var s = time.getSeconds();
return y+'-'+add0(m)+'-'+add0(d)+' '+add0(h)+':'+add0(mm)+':'+add0(s);
}

三.封装的时间格式器

/**
* 和PHP一样的时间戳格式化函数
* @param {string} format 格式
* @param {int} timestamp 要格式化的时间默认为当前时间
* @return {string} 格式化的时间字符串
*/
function date(format, timestamp){
var a, jsdate=((timestamp) ? new Date(timestamp*1000) : new Date());
var pad = function(n, c){
if((n = n + "").length < c){
return new Array(++c - n.length).join("0") + n;
} else {
return n;
}
};
var txt_weekdays = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
var txt_ordin = {1:"st", 2:"nd", 3:"rd", 21:"st", 22:"nd", 23:"rd", 31:"st"};
var txt_months = ["", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
var f = {
// Day
d: function(){return pad(f.j(), 2)},
D: function(){return f.l().substr(0,3)},
j: function(){return jsdate.getDate()},
l: function(){return txt_weekdays[f.w()]},
N: function(){return f.w() + 1},
S: function(){return txt_ordin[f.j()] ? txt_ordin[f.j()] : 'th'},
w: function(){return jsdate.getDay()},
z: function(){return (jsdate - new Date(jsdate.getFullYear() + "/1/1")) / 864e5 >> 0},

// Week
W: function(){
var a = f.z(), b = 364 + f.L() - a;
var nd2, nd = (new Date(jsdate.getFullYear() + "/1/1").getDay() || 7) - 1;
if(b <= 2 && ((jsdate.getDay() || 7) - 1) <= 2 - b){
return 1;
} else{
if(a <= 2 && nd >= 4 && a >= (6 - nd)){
nd2 = new Date(jsdate.getFullYear() - 1 + "/12/31");
return date("W", Math.round(nd2.getTime()/1000));
} else{
return (1 + (nd <= 3 ? ((a + nd) / 7) : (a - (7 - nd)) / 7) >> 0);
}
}
},

// Month
F: function(){return txt_months[f.n()]},
m: function(){return pad(f.n(), 2)},
M: function(){return f.F().substr(0,3)},
n: function(){return jsdate.getMonth() + 1},
t: function(){
var n;
if( (n = jsdate.getMonth() + 1) == 2 ){
return 28 + f.L();
} else{
if( n & 1 && n < 8 || !(n & 1) && n > 7 ){
return 31;
} else{
return 30;
}
}
},

// Year
L: function(){var y = f.Y();return (!(y & 3) && (y % 1e2 || !(y % 4e2))) ? 1 : 0},
//o not supported yet
Y: function(){return jsdate.getFullYear()},
y: function(){return (jsdate.getFullYear() + "").slice(2)},

// Time
a: function(){return jsdate.getHours() > 11 ? "pm" : "am"},
A: function(){return f.a().toUpperCase()},
B: function(){
// peter paul koch:
var off = (jsdate.getTimezoneOffset() + 60)*60;
var theSeconds = (jsdate.getHours() * 3600) + (jsdate.getMinutes() * 60) + jsdate.getSeconds() + off;
var beat = Math.floor(theSeconds/86.4);
if (beat > 1000) beat -= 1000;
if (beat < 0) beat += 1000;
if ((String(beat)).length == 1) beat = "00"+beat;
if ((String(beat)).length == 2) beat = "0"+beat;
return beat;
},
g: function(){return jsdate.getHours() % 12 || 12},
G: function(){return jsdate.getHours()},
h: function(){return pad(f.g(), 2)},
H: function(){return pad(jsdate.getHours(), 2)},
i: function(){return pad(jsdate.getMinutes(), 2)},
s: function(){return pad(jsdate.getSeconds(), 2)},
//u not supported yet

// Timezone
//e not supported yet
//I not supported yet
O: function(){
var t = pad(Math.abs(jsdate.getTimezoneOffset()/60*100), 4);
if (jsdate.getTimezoneOffset() > 0) t = "-" + t; else t = "+" + t;
return t;
},
P: function(){var O = f.O();return (O.substr(0, 3) + ":" + O.substr(3, 2))},
//T not supported yet
//Z not supported yet

// Full Date/Time
c: function(){return f.Y() + "-" + f.m() + "-" + f.d() + "T" + f.h() + ":" + f.i() + ":" + f.s() + f.P()},
//r not supported yet
U: function(){return Math.round(jsdate.getTime()/1000)}
};

return format.replace(/[\]?([a-zA-Z])/g, function(t, s){
if( t!=s ){
// escaped
ret = s;
} else if( f[s] ){
// a date function exists
ret = f[s]();
} else{
// nothing special
ret = s;
}
return ret;
});
}

调用方法能够很方便的将时间戳转换成日期的格式，如：

date('Y-m-d','1350052653');//很方便的将时间戳转换成了2012-10-11
date('Y-m-d H:i:s','1350052653');//得到的结果是2012-10-12 22:37:33
