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);
}
