Method

StringformatTimeSec(long time)
Generates string representation of given time specified as long. 
StringBuffer str = new StringBuffer();
if (time < 60) {
    str.append(time + " sec");
    return str.toString();
int days = (int) time / 86400;
if (days != 0) {
    str.append(days + " days");
...
StringformatTimespan(int timespan)
format Timespan 
String result = "";
int years = timespan / 31536000;
if (years > 0) {
    timespan -= years * 31536000;
    result += String.format(" %dy", years);
int months = timespan / 2592000;
if (months > 0) {
...
StringformatTimeSpanForScheduler(long time)
Format a timespan given in ms as human readable output (using weeks as the maximum time unit and seconds as the smallest) 
if (time < 0)
    return "-";
StringBuilder res = new StringBuilder(10);
long s = time / 1000;
long min = 0;
long hr = 0;
long d = 0;
long w = 0;

StringBuffer stringBuffer = new StringBuffer(tempTimeStamp);
return tempTimeStamp = stringBuffer.substring(0, 13);
StringformatTimestampEnd(String timestamp)
Formats a string timestamp to be used as the end bound filter string in HBase scan. 
if (timestamp == null || timestamp == "")
    return timestamp;

format Time Step 
return String.format("%.3f", (double) stepNumber / numberOfTimestepsPerYear);
StringformatTimeString(long millisecond)
Milliseconds -> hh:mm:ss 
millisecond = millisecond < 0 ? -millisecond : millisecond;
int seconds = (int) (millisecond / 1000);
StringBuffer result = new StringBuffer("");
int ss = seconds % 60;
