Method

StringformatDuration(long duration)
format Duration 
long hours = TimeUnit.MILLISECONDS.toHours(duration);
long minutes = TimeUnit.MILLISECONDS.toMinutes(duration) - (hours * 60);
long seconds = TimeUnit.MILLISECONDS.toSeconds(duration) - (hours * 60 * 60) - (minutes * 60);
long milliseconds = TimeUnit.MILLISECONDS.toMillis(duration) - (hours * 60 * 60 * 1000)
        - (minutes * 60 * 1000) - (seconds * 1000);
StringBuilder builder = new StringBuilder();
if (hours > 0) {
    builder.append(hours);
...
StringformatDuration(long millis)
This will return a rounded String representation of the given duration in milliseconds with a minimum of 1 time unit and a maximum of 2 time units.
Examples:
  • 3785300: 1 hr, 3 min
  • 81074000: 22 hrs, 31 min
  • 97440000: 1 day, 3 hrs
  • 478200: 7 minutes
  • 18056000: 5 hours
String formattedTimer = "";
int days = (int) TimeUnit.MILLISECONDS.toDays(millis);
long hours = TimeUnit.MILLISECONDS.toHours(millis) - (days * 24);
long minutes = TimeUnit.MILLISECONDS.toMinutes(millis) - (TimeUnit.MILLISECONDS.toHours(millis) * 60);
long seconds = TimeUnit.MILLISECONDS.toSeconds(millis) - (TimeUnit.MILLISECONDS.toMinutes(millis) * 60);
if (days != 0) {
    formattedTimer += days + " day" + (days > 1 ? "s" : "");
if (hours != 0) {
    String unit = (days > 0 || (days == 0 && minutes > 0) ? " hr" : " hour") + (hours > 1 ? "s" : "");
    formattedTimer += (formattedTimer.length() != 0 ? ", " : "") + hours + unit;
if (minutes != 0 && days == 0) {
    String unit = (hours > 0) ? " min" : " minute" + (minutes > 1 ? "s" : "");
    formattedTimer += (formattedTimer.length() != 0 ? ", " : "") + minutes + unit;
if (seconds != 0 && days == 0 && hours == 0 && minutes == 0) {
    String unit = " second" + (seconds > 1 ? "s" : "");
    formattedTimer += (formattedTimer.length() != 0 ? ", " : "") + seconds + unit;
return !formattedTimer.isEmpty() ? formattedTimer : "0 seconds";
StringformatDuration(long millis)
Duration in the form - PTHH:mm:ss.mmm P is period or duration and T designates a time in ISO8601 format. 
if (millis < 0) {
    throw new IllegalArgumentException(String.format("Duration: %d is < 0", millis));
long hours = TimeUnit.MILLISECONDS.toHours(millis);
millis -= TimeUnit.HOURS.toMillis(hours);
long minutes = TimeUnit.MILLISECONDS.toMinutes(millis);
millis -= TimeUnit.MINUTES.toMillis(minutes);
long seconds = TimeUnit.MILLISECONDS.toSeconds(millis);
...
StringformatDuration(long time)
format Duration 
long millis = time;
long days = TimeUnit.MILLISECONDS.toDays(millis);
millis -= TimeUnit.DAYS.toMillis(days);
long hours = TimeUnit.MILLISECONDS.toHours(millis);
millis -= TimeUnit.HOURS.toMillis(hours);
long minutes = TimeUnit.MILLISECONDS.toMinutes(millis);
millis -= TimeUnit.MINUTES.toMillis(minutes);
long seconds = TimeUnit.MILLISECONDS.toSeconds(millis);
...
StringformatDurationSeconds(long seconds)
format Duration Seconds 
long x = seconds;
long days = x / SECONDS_PER_DAY;
x %= SECONDS_PER_DAY;
int years = (int) (days / 365);
days -= (years * 365);
int months = (int) (days * 12d / 365d);
String m = (months == 1) ? "month" : "months";
if (years > 5)
...
StringformatDurationTill(long start)
Calculate the duration between now and the given time Taken mostly from http://stackoverflow.com/a/5062810/207604 . 
long duration = System.currentTimeMillis() - start;
StringBuilder res = new StringBuilder();
TimeUnit current = HOURS;
while (duration > 0) {
    long temp = current.convert(duration, MILLISECONDS);
    if (temp > 0) {
        duration -= current.toMillis(temp);
        res.append(temp).append(" ").append(current.name().toLowerCase());
...
StringformatElapsedSecs(long secs)
Formats an elapsed time in seconds as days, hh:mm:ss. 
long eTime = secs;
final long days = TimeUnit.SECONDS.toDays(eTime);
eTime -= TimeUnit.DAYS.toSeconds(days);
final long hr = TimeUnit.SECONDS.toHours(eTime);
eTime -= TimeUnit.HOURS.toSeconds(hr);
final long min = TimeUnit.SECONDS.toMinutes(eTime);
eTime -= TimeUnit.MINUTES.toSeconds(min);
final long sec = eTime;
...
StringformatElapsedTime(final long seconds)
Formats elapsed time in seconds to form days:hours:minutes:seconds. 
Preconditions.checkArgument(seconds >= 0);
return String.format("%1d:%02d:%02d:%02d", TimeUnit.SECONDS.toDays(seconds),
        TimeUnit.SECONDS.toHours(seconds) - TimeUnit.DAYS.toHours(TimeUnit.SECONDS.toDays(seconds)),
        TimeUnit.SECONDS.toMinutes(seconds) - TimeUnit.HOURS.toMinutes(TimeUnit.SECONDS.toHours(seconds)),
        seconds - TimeUnit.MINUTES.toSeconds(TimeUnit.SECONDS.toMinutes(seconds)));
StringformatElapsedTime(long elapsedTimeMs)
Return a prettified version of the given elapsed time in milliseconds. 
if (elapsedTimeMs < 1000) {
    return String.format("%d ms", elapsedTimeMs);
long seconds = TimeUnit.MILLISECONDS.toSeconds(elapsedTimeMs) % 60;
long minutes = TimeUnit.MILLISECONDS.toMinutes(elapsedTimeMs) % 60;
long hours = TimeUnit.MILLISECONDS.toHours(elapsedTimeMs);
StringBuilder time = new StringBuilder();
if (hours > 0) {
...
StringformatElapsedTime(long millis)
format Elapsed Time 
long d = TimeUnit.MILLISECONDS.toDays(millis);
long h = TimeUnit.MILLISECONDS.toHours(millis) % TimeUnit.DAYS.toHours(1);
long m = TimeUnit.MILLISECONDS.toMinutes(millis) % TimeUnit.HOURS.toMinutes(1);
long s = TimeUnit.MILLISECONDS.toSeconds(millis) % TimeUnit.MINUTES.toSeconds(1);
if (d > 0)
    return String.format("%02d d, %02d h, %02d m, %02d s", d, h, m, s);
if (h > 0)
    return String.format("%02d h, %02d m, %02d s", h, m, s);
