  public static void main(String[] argv) throws Exception {



    File file = new File("filename");



    long modifiedTime = file.lastModified();

    // 0L is returned if the file does not exist



    long newModifiedTime = System.currentTimeMillis();

    boolean success = file.setLastModified(newModifiedTime);

    if (!success) {
