Use `utime'.  Not only does it support LFNs (in v2.01) and can set both
access and modification times on LFN platforms, but it also is more
portable (it's POSIX AFAIK).

You better not rely on this for files that are open for writing, because 
usually closing such files also changes the time stamp.  If I understand 
your situation correctly, using `utime' is easier since you don't have to 
reopen the file.
