Gets the time, in coordinated universal time (UTC), when the current file or directory was last written to.
Returns
The UTC time when the current file was last written to.
Note
This method may return an inaccurate value because it uses native functions whose values may not be continuously updated by the operating system.
Remarks
The value of the LastWriteTimeUtc property is pre-cached if the current instance of the FileSystemInfo object was returned from any of the following xtd::io::directory_info methods:
If the file or directory described in the xtd::io::file_system_info object does not exist, or if the file system that contains this file or directory does not support this information, this property returns 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC).
