(转)How to convert milliseconds into human readable form?

x = ms / 1000
seconds = x % 60
x /= 60
minutes = x % 60
x /= 60
hours = x % 24
x /= 24
days = x

public static String formatMs(long millis) {
    long hours = TimeUnit.MILLISECONDS.toHours(millis);
    long mins = TimeUnit.MILLISECONDS.toMinutes(millis);
    long secs = TimeUnit.MILLISECONDS.toSeconds(millis);
    return String.format("%dh %d min, %d sec",
            hours,
            mins - TimeUnit.HOURS.toMinutes(hours),
            secs - TimeUnit.MINUTES.toSeconds(mins)
    );
