// 对Date的扩展，将 Date 转化为指定格式的String
|
||
// 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符，
|
||
// 年(y)可以用 1-4 个占位符，毫秒(S)只能用 1 个占位符(是 1-3 位的数字)
|
||
// 例子：
|
||
// (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423
|
||
// (new Date()).Format("yyyy-M-d h:m:s.S") ==> 2006-7-2 8:9:4.18
