Ext.util.Format.date 时间格式的设置与转换

Ext.util.Format.date

如下这段简单的代码： 

var d = new Date(value.time);
var s = Ext.util.Format.date(d, 'Y-m-d H:m:s');
return s;

在Chrome的Develop Tools中断点调试，发现这些变量的值为：
value.time: 1396257528000
d: Mon Mar 31 2014 17:18:48 GMT+0800 (中国标准时间)
s: "2014-03-31 17:03:48"
年月日时分秒中，只有分钟不对，硬生生的差了15分钟，汗！
单步跟踪进去，发现是Extjs的源码（VM13060）里有问题，竟然用月份代替了分钟：

(function() {
    var Ext = window.ExtBox1;
    return Ext.String.leftPad(this.getFullYear(), 4, '0') + '-' + Ext.String.leftPad(this.getMonth() + 1, 2, '0') + '-'
        + Ext.String.leftPad(this.getDate(), 2, '0') + ' ' + Ext.String.leftPad(this.getHours(), 2, '0') + ':'
        + Ext.String.leftPad(this.getMonth() + 1, 2, '0') + ':' + Ext.String.leftPad(this.getSeconds(), 2, '0')
})

仔细一想，发现是分钟（minute）与月份（month）搞错了，分钟应该用i而不是m

Ext.util.Format.date(d, 'Y-m-d H:i:s');

Extjs的源码里有各种格式的功能的：

formatCodes : {
    d: "Ext.String.leftPad(this.getDate(), 2, '0')",
    D: "Ext.Date.getShortDayName(this.getDay())",
    j: "this.getDate()",
    l: "Ext.Date.dayNames[this.getDay()]",
    N: "(this.getDay() ? this.getDay() : 7)",
    S: "Ext.Date.getSuffix(this)",
    w: "this.getDay()",
    z: "Ext.Date.getDayOfYear(this)",
    W: "Ext.String.leftPad(Ext.Date.getWeekOfYear(this), 2, '0')",
    F: "Ext.Date.monthNames[this.getMonth()]",
    m: "Ext.String.leftPad(this.getMonth() + 1, 2, '0')",
    M: "Ext.Date.getShortMonthName(this.getMonth())",
    n: "(this.getMonth() + 1)",
    t: "Ext.Date.getDaysInMonth(this)",
    L: "(Ext.Date.isLeapYear(this) ? 1 : 0)",
    o: "(this.getFullYear() + (Ext.Date.getWeekOfYear(this) == 1 && this.getMonth() > 0 ? +1 : "
"(Ext.Date.getWeekOfYear(this) >= 52 && this.getMonth() < 11 ? -1 : 0)))",
    Y: "Ext.String.leftPad(this.getFullYear(), 4, '0')",
    y: "('' + this.getFullYear()).substring(2, 4)",
    a: "(this.getHours() < 12 ? 'am' : 'pm')",
    A: "(this.getHours() < 12 ? 'AM' : 'PM')",
    g: "((this.getHours() % 12) ? this.getHours() % 12 : 12)",
    G: "this.getHours()",
    h: "Ext.String.leftPad((this.getHours() % 12) ? this.getHours() % 12 : 12, 2, '0')",
    H: "Ext.String.leftPad(this.getHours(), 2, '0')",
    i: "Ext.String.leftPad(this.getMinutes(), 2, '0')",
    s: "Ext.String.leftPad(this.getSeconds(), 2, '0')",
    u: "Ext.String.leftPad(this.getMilliseconds(), 3, '0')",
    O: "Ext.Date.getGMTOffset(this)",
    P: "Ext.Date.getGMTOffset(this, true)",
    T: "Ext.Date.getTimezone(this)",
    Z: "(this.getTimezoneOffset() * -60)",
    c: function() {
for (var c = "Y-m-dTH:i:sP", code = [], i = 0, l = c.length; i < l; ++i) {
var e = c.charAt(i);
            code.push(e == "T" ? "'T'" : utilDate.getFormatCode(e));
        }
return code.join(" + ");
    },
    U: "Math.round(this.getTime() / 1000)"
},
