Method

doublesecondsToHours(double seconds)
seconds To Hours 
return seconds / 3600.0;
StringsecondsToHours(int s)
seconds To Hours 
int h = s / 3600;
int q = s % 3600;
int m = q / 60;
int ss = q % 60;
return align(h) + ":" + align(m) + ":" + align(ss);
intsecondsToInternal(int seconds)
Helper method that converts from seconds into internal time unit (which is approximately "quarter of a second") 
if (seconds < MAX_SECONDS_FOR_INT) {
    return (seconds * 1000) >>> 8;
long msecs = 1000L * seconds;
return (int) (msecs >>> 8);
longsecondsToNanoseconds(long seconds)
seconds To Nanoseconds 
return seconds * 1000000000;
StringsecondsToReadableBiggest(int seconds)
Changes the amount of seconds to its biggest part
More then an hour returns "xx hour"
Less then an hour but more then a minute returns "xx min"
Otherwise returns "xx sec" 
if (seconds > 60 * 60)
    return Math.round(seconds / (60 * 60)) + " hour";
else if (seconds > 60)
    return Math.round(seconds / 60) + " min";
else
    return seconds + " sec";
StringsecondsToString(int seconds)
seconds To String 
int h = seconds / (60 * 60);
int m = seconds / 60 % 60;
int s = seconds % 60;
return toStr2(h) + ":" + toStr2(m) + (s == 0 ? "" : ":" + toStr2(s));
StringsecondsToString(long seconds)
seconds To String 
long h = seconds / 3600;
long m = (seconds - (h * 3600)) / 60;
long s = seconds - (h * 3600) - (m * 60);
return String.format("%02d:%02d:%02d", h, m, s);
StringSecondsToString(long seconds)
Formats number of seconds to a string consists of number of seconds, minutes, hours or days and the corresponding entity (e.g. 
String timeString = null;
if (seconds < 60) {
    timeString = seconds + " seconds";
} else if (seconds < 3600) {
    timeString = (seconds / 60) + " minutes";
} else if (seconds < 86400) {
    timeString = (seconds / 3600) + " hours";
} else {
...
StringsecondsToString(long seconds)
Converts seconds from long to a String in the format "mm:ss". 
if (seconds < 0) {
    seconds = seconds * -1;
return String.format("%02d:%02d", seconds / 60, seconds % 60);
StringsecondsToString(long time)
seconds To String 
return millisecondsToString(time * 1000);
