I believe the original poster was working on Windows(TM), so this
isn't strictly relevant, but for general knowledge I'll mention that on
unix, the open() mentioned above will not work, and changing the time
requires superuser privilege.  To touch the file using file methods, you'll
have to actually write to it.  E.g., read the first byte from the file and then
write it back (which won't work with a zero-length file), or seek to the end,
write a byte, then back up one byte and truncate at the file position.
