Method

longmillisToSeconds(final long millis)
Converts millis to seconds 
return Math.round(millis / 1000.0);
longmillisToSeconds(long millis)
Rounds the number of milliseconds relative to the epoch down to the nearest whole number of seconds. 
if (millis >= 0) {
    return millis / 1000;
} else {
    return (millis - 999) / 1000;
StringmillisToSeconds(long millis)
Converts time in milliseconds to a String representing the time in seconds in the format XX.XXX 
String result = "";
String complement = "";
long fraction = Math.abs(millis) % 1000;
if (fraction < 10) {
    complement = "00";
} else if (fraction < 100) {
    complement = "0";
result += millis / 1000;
result += ".";
result += complement + fraction;
return result;
longmillisToSeconds(long millis)
millis To Seconds 
return millis / 1000;
StringmillisToShortDHMS(long duration)
converts time (in milliseconds) to human-readable format "hh:mm:ss" 
String res = "";
duration /= ONE_SECOND;
int seconds = (int) (duration % SECONDS);
duration /= SECONDS;
int minutes = (int) (duration % MINUTES);
duration /= MINUTES;
int hours = (int) (duration % HOURS);
int days = (int) (duration / HOURS);
...
StringmillisToString(float millis)
millis To String 
int s = (int) millis % 60;
int m = ((int) ((millis / 60) % 60));
return (m < 10 ? "0" : "") + m + ":" + (s < 10 ? "0" : "") + s;
StringmillisToString(long millis)
millis To String 
int length = (int) Math.floor(millis / 1000D);
int hours = (int) Math.floor(length / 60D / 60D);
length -= hours * 60 * 60;
int minutes = (int) Math.floor(length / 60D);
length -= minutes * 60;
return (hours > 0 ? hours + ":" : "") + (minutes < 10 & hours > 0 ? "0" : "") + minutes + ":"
        + (length < 10 ? "0" + length : length);
StringmillisToString(long ms)
millis To String 
int days = (int) (ms / (1000 * 60 * 60 * 24)) % 7;
int hours = (int) (ms / (1000 * 60 * 60)) % 24;
int mins = (int) (ms / (1000 * 60)) % 60;
int secs = (int) (ms / 1000) % 60;
if (days > 0) {
    return String.format("%s days, %sh %sm %ss", days, hours, mins, secs);
} else if (hours > 0) {
    return String.format("%sh %sm %ss", hours, mins, secs);
...
StringmillisToString(long t)
millis To String 
StringBuilder sb = new StringBuilder();
long frac = t / 3600000L;
if (frac > 0) {
    sb.append(frac).append("h");
    t = t - frac * 3600000;
frac = t / 60000;
if (frac > 0) {
...
StringmillisToStringDouble(double millis)
millis To String Double 
double seconds = millis / 1000d;
long hours = (long) (seconds / 3600);
long minutes = (long) ((seconds % 3600) / 60);
double remaining = (seconds % 3600d) % 60d;
String output = "";
output = output.concat(String.format("%02d:", hours));
output = output.concat(String.format("%02d:", minutes));
String stringifiedSeconds = decimalFormat.format(remaining);
