Compares the value of two FileTime objects for order.

Usage

From source file:Main.java

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

    long time = System.currentTimeMillis();
    FileTime fileTime = FileTime.fromMillis(time);

    FileTime fileTime1 = FileTime.from(time, TimeUnit.MILLISECONDS);

    System.out.println(fileTime.compareTo(fileTime1));
