<Result>: Character string
  • Time associated with the file or directory (in HHMMSS format),
  • Empty string ("") if an error occurred. To find out the error details, use ErrorInfo associated with the errMessage constant.
<File or directory path>: Character string (with quotes)
  • Name and full (or relative) path of file (up to 260 characters).
  • Full (or relative) path of directory (up to 260 characters).
A UNC path can be used. If this parameter corresponds to a directory name, this name may (or may not) end with "\".

Modifying the date and time associated with a file

To modify the date and time associated with a file, you have the ability to use fDateTime.
Remark: You also have the ability to use fDate and fTime successively. However, fDateTime is faster.

Managing the seconds

All the methods for disk formatting (FAT, NTSF, ...) are not precise to the second. Depending on the method used, fTime may round the time passed in parameter.
For example, for a FAT drive, the time for file access has a precision of one day. Therefore, the access time is "000000" and it cannot be modified.

Managing errors

fTime generates an error in the following cases:
  • the specified file is opened or locked by another application,
  • the specified file does not exist,
  • the name of the specified file is invalid,
  • the format of <New time> is incorrect. A WLanguage error occurs if the format of <New time> is incorrect.
  • a Unicode string was used for <Path of file or directory> in an operating system such as Windows 98 or Windows Me.

Operating mode in Windows Vista (and later)

If this function does not operate properly in Windows Vista (and later), check whether the file or directory used is not in one of the system directories (Windows directory or "Program Files" directory).
Indeed, in Windows Vista (and later), with the UAC mechanism (User Account Control) enabled, you must have the administrator privileges to handle and/or modify the files or directories in the system directories (Windows directory or "Program Files" directory).
Programming tip: To handle and/or modify the files or directories without administrator privileges, you should:
  • avoid writing into the Windows directory or into the "Program Files" directory,
  • use the system directory corresponding to the application (returned by SysDir associated with the srCommonAppData constant).

Operating mode in the different operating systems

  • The time associated with a file or a directory cannot be modified in the following systems: Windows 98, Windows ME.
Component : wd240std.dll
Minimum version required
  • Version 9
