从日期时间类型数值里面解析出时、分、秒、毫秒

头文件：#include <System.SysUtils.hpp>
命名空间：System::Sysutils
函数原型：

void __fastcall DecodeTime(const System::TDateTime DateTime, System::Word &Hour, System::Word &Min, System::Word &Sec, System::Word &MSec);

参数：

• DateTime：日期时间类型变量；
• Hour：返回时，0 ~ 23；
• Min：返回分，0 ~ 59；
• Sec：返回秒，0 ~ 59；
• MSec：返回毫秒，0 ~ 999；

返回值：

• 无，解析结果通过参数 Hour, Min, Sec, MSec 返回。

例：

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    System::TDateTime dt = Sysutils::Now();
    unsigned short uHour, uMin, uSec, uMSec;
    Sysutils::DecodeTime(dt, uHour, uMin, uSec, uMSec);
    UnicodeString s;
    s.sprintf(L"现在时间是 %d:%02d:%02d.%03d", uHour, uMin, uSec, uMSec);
    Memo1->Lines->Add(s);
}

运行结果：
