Set file creation/change time in touch

Description

With the touch function you can set the modification and access time, but not the creation/change time. I have several Windows applications where I need to set the creation time, for example a backup tool that needs to preserve the creation time. I have solved that with a C program that can set creation, modification and access times and that can be invoked from PHP using (Unix) sockets. But that is a relatively complicated solution, it would be much simpler/neater if you could set the creation time using touch.
It would also be nice if the copy function would have a flag to preserve ctime, mtime and a time. In that case a touch to reset ctime, mtime and atime would not be needed at all. But I have a PHP tool that sets ctime and mtime of JPG files based on the ctime and mtime in the Exif header, for that I need the touch solution. A flag in the copy function would be a partial solution, setting ctime with touch is a more general and complete solution.

Beginne damit, die bestehenden touch- und copy-Einstiegspunkte in PHP zu überprüfen, und untersuche anschließend, wie Windows die Erstellungszeit im Vergleich zu Änderungs- und Zugriffszeiten darstellt. Lege die unterstützte Semantik zum Setzen oder Beibehalten dieser Zeitstempel fest und überprüfe das Verhalten auf den relevanten Plattformen; als erledigt gilt die Aufgabe, wenn die angeforderte Behandlung der Zeitstempel spezifiziert und durch Tests abgedeckt ist.
