動作確認
C++ Builder XE4
Rad Studio 10.2 Tokyo Update 2 (追記: 2017/12/26)

ファイルのタイムスタンプを取得したい。

参考1: http://mrxray.on.coocan.jp/Delphi/plSamples/780_FileInfoListETC.htm

参考2: http://www.gesource.jp/weblog/?p=3117

以下で取得できた。

TDateTime dt;
FileAge(filename, dt);
String dtstr = DateTimeToStr(dt);

を見てもC++ Builderでは bool FileAge(const System::UnicodeString FileName, System::TDateTime &FileDateTime);の方の記載がない。。。 XE8のヘルプにも載っていない。
