Method

Timestampadd(Timestamp target, int addNum, int addKind)
add 
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(target);
cal.add(addKind, addNum);
return new Timestamp(new Date(cal.getTimeInMillis()).getTime());
Timestampadd(Timestamp ts, int field, int amount)
add 
Calendar cal = Calendar.getInstance();
cal.setTime(ts);
cal.add(field, amount);
Timestamp ts2 = new Timestamp(cal.getTime().getTime());
return ts2;
TimestampaddDate(Timestamp date, String type, int into)
add Date 
GregorianCalendar grc = new GregorianCalendar();
grc.setTime(new java.util.Date(date.getTime()));
if (type.equals("D")) {
    grc.add(GregorianCalendar.DATE, into);
} else if (type.equals("M")) {
    grc.add(GregorianCalendar.MONTH, into);
} else if (type.equals("Y")) {
    grc.add(GregorianCalendar.YEAR, into);
...
TimestampaddDays(Timestamp date, int days)
add Days 
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.DATE, days); 
return new Timestamp(cal.getTime().getTime());
TimestampaddDays(Timestamp day, int offset)
Return Day + offset (truncates) 
if (day == null)
    day = new Timestamp(System.currentTimeMillis());
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(day);
cal.set(Calendar.HOUR_OF_DAY, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
...
TimestampaddDaysToTimestamp(Timestamp start, int days)
add Days To Timestamp 
return new Timestamp(start.getTime() + (24L * 60L * 60L * 1000L * days));
TimestampaddDaysToTimestamp(Timestamp timestamp, int numDays)
Adds the specified number of Days to the specified Date object To subtract the specified number of Days to the specified Date object, juz use a negative number Example: DateUtil.addDaysToDate(date, -5) == subtracting 5 days from the specified date. 
if (timestamp == null) {
    return null;
Calendar c = Calendar.getInstance();
c.setTime(timestamp);
c.add(Calendar.DATE, numDays);
return new Timestamp(c.getTimeInMillis());
TimestampaddHours(Timestamp date, int numOfHours)
add Hours 
Long milliSecInAnHour = new Long(60 * 60 * 1000);
Timestamp newTS = new Timestamp(date.getTime());
long milliSecToAdd = milliSecInAnHour * numOfHours;
long newTimeMilliSec = newTS.getTime();
newTS.setTime(newTimeMilliSec + milliSecToAdd);
return newTS;
TimestampaddHoursToTimestamp(Timestamp start, int hours)
add Hours To Timestamp 
return new Timestamp(start.getTime() + (60L * 60L * 1000L * hours));
TimestampaddMilli(Timestamp nowDate, int period)
addMilli.
Calendar calendar = Calendar.getInstance();
calendar.setTime(nowDate);
calendar.add(Calendar.MILLISECOND, period);
Timestamp stopTerm = date2Timestamp(calendar.getTime());
return stopTerm;
