Horst, if you were serious about it, you could write a program to change the date, touch the file, and change the date again. I'd be surprised if the system time were changed for more than a millisecond.
But yes, that's the best you can do. The ctime is not supposed to be user-settable. I don't think anyone has mentioned the utime() and utimes() system calls. The latter lets you set a file's atime and mtime with microsecond resolution. (How much of that resolution is actually stored depends on the filesystem.)
