Try the SysUtils.FileSetDate function from the SysUtils block, which internally calls the SetFileTime WinApi function.

this function has two versions

 function FileSetDate(const FileName: string; Age: Integer): Integer; function FileSetDate(Handle: THandle; Age: Integer): Integer;

The Age parameter is the installation time. To convert a TDateTime value to a Windows timestamp.

Like this

 FileSetDate(FileName, DateTimeToFileDate(Now));

In the IOUtils.pas block IOUtils.pas you can find the corresponding methods in the TFile and TDirectory : SetCreationTime , SetLastAccesstime , SetLastWriteTime , followed by their UTC syntax errors.
