Method

Stringtimestamp2string()
timestampstring 
return String.valueOf(System.currentTimeMillis() / 1000);
byte[]timestamp4(int unixTime)
http://stackoverflow.com/questions/29273498/getting-date-time-in-unix-time-as-byte-array-which-size-is-4-bytes-with-java 
byte[] productionDate = new byte[] { (byte) (unixTime >> 24), (byte) (unixTime >> 16),
        (byte) (unixTime >> 8), (byte) unixTime };
return productionDate;
StringtimestampDifference(long ts1, long ts2)
timestamp Difference 
long difference = (ts1 - ts2) / 1000; 
if (difference <= 0) {
    return "0 second";
String strIntervals[][] = new String[][] { new String[] { "year", "years" },
        new String[] { "month", "months" }, new String[] { "week", "weeks" },

longtimestampMicros()
timestamp Micros 
return System.currentTimeMillis() * 1000;
byte[]timestampNonce(final int length)
Generates a nonce of the given size by repetitively concatenating system timestamps (i.e. 
if (length <= 0) {
    throw new IllegalArgumentException(length + " is invalid. Length must be positive.");
final byte[] nonce = new byte[length];
int count = 0;
long timestamp;
while (count < length) {
    timestamp = System.nanoTime();
...
longtimestampNow()
timestamp Now 
return System.currentTimeMillis();
longtimestampStartOfDay(long time)
timestamp Start Of Day 
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(time);
cal.set(Calendar.HOUR_OF_DAY, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
return cal.getTimeInMillis();
longtimestampStringToUnixDate(String s)
timestamp String To Unix Date 
final long d;
final long t;
s = s.trim();
int space = s.indexOf(' ');
if (space >= 0) {
    d = dateStringToUnixDate(s.substring(0, space));
    t = timeStringToUnixDate(s, space + 1);
} else {
...
java.sql.TimestamptoOracleTimestamp(String stringDate, int intFlag)
given format of dd/mm/yyyy, and return Timestamp yyyy-mm-dd hh:mm:ss.000000000 

java.sql.Timestamp oracleDate = null;
if (stringDate == null)
    return null;
try {
    oracleDate = java.sql.Timestamp.valueOf(toOracleDatetime(stringDate, intFlag));
} catch (Exception e) {
    return null;

java.sql.TimestamptoSQLTime(Instant timestamp)
Convert EPICS time stamp into SQL time stamp 
final java.sql.Timestamp sql = new java.sql.Timestamp(timestamp.toEpochMilli());
sql.setNanos(timestamp.getNano());
return sql;
