Fs. futimes (fd, 1388648322,138 8648322, function (err ){
If (err ){
Throw err;
}
Console. log ('futimes complete ');
Fs. close (fd, function (){
Console. log ('done ');
});
});
});

Fs. futimes = function (fd, atime, mtime, callback ){
Atime = toUnixTimestamp (atime );
Mtime = toUnixTimestamp (mtime );
Binding. futimes (fd, atime, mtime, makeCallback (callback ));
};
