Maybe it could be an idea and check both ctime and mtime? I created
the following function before I planed to start the implementation:

new in monitor.h:

#define MAX(x,y)           ((x) > (y) ? (x) : (y))

in util.c:

 * Get a files last modified timestamp. This function returns the max
 * of either st_mtime or st_ctime. If the file does not exist or is
 * not a regular file FALSE is returned
 * @param file A file to stat
 * @return last modification time or FALSE if not found or not a regular file
long getchange_file(char *file) {
  struct stat buf;

  if(!stat(file, &buf))
          return MAX(buf.st_mtime, buf.st_ctime);
  return FALSE;
