Method

longnanosecondsToSeconds(long nanoseconds)
nanoseconds To Seconds 
return (long) (nanoseconds / NANOS_PER_SECOND);
StringnanosecondsToString(long ns)
Format a long representing nanoseconds into a string of the form "[seconds].[nanoseconds]" with the appropriate zero-padding. 
ns = Math.abs(ns);
String time = Long.toString(ns);
int length = time.length();
if (time.length() > 9) {
    time = time.substring(0, length - 9) + "." + time.substring(length - 9); 
    return time;
for (int i = length; i < 9; i++) {
...
doublenanoSecondToSecond(double nano, int decimal)
Convert from nano second to second 
double precision = Math.pow(10, decimal);
double second = nano / 1_000_000_000d;
return Math.round(second * precision) / precision;
StringnanoSecToString(final long nS)
Returns the given time in nanoseconds formatted as Sec.mSec uSec nSec 
final long rem_nS = (long) (nS % 1000.0);
final long rem_uS = (long) ((nS / 1000.0) % 1000.0);
final long rem_mS = (long) ((nS / 1000000.0) % 1000.0);
final long sec = (long) (nS / 1000000000.0);
final String nSstr = zeroPad(Long.toString(rem_nS), 3);
final String uSstr = zeroPad(Long.toString(rem_uS), 3);
final String mSstr = zeroPad(Long.toString(rem_mS), 3);
return String.format("%d.%3s %3s %3s", sec, mSstr, uSstr, nSstr);
...
intnanosForFractionalValue(int value, int width)
nanos For Fractional Value 
switch (width) {
case 0:
    return 0;
case 1:
    return value * 10000000;
case 2:
    return value * 100000;
case 3:
...
longnanoTime()
Equivalent to System.nanoTime(), but based off the 1/1/1970 epoch like currentTimeMillis(). 
return System.nanoTime() + nanoTimeOffset;
longnanoTime()
nano Time 
return System.nanoTime();
booleannanoTimeLessThan(long leftNanos, long rightNanos)
Compare two nanosecond times. 
return ((leftNanos - rightNanos) < 0L);
doublenanoTimeToSeconds(long nanoTime)
nano Time To Seconds 
return nanoTime / 1000000000.0;
floatnanoToMilli(double nanoseconds)
nano To Milli 
return (float) nanoseconds / 1000 / 1000;
