If you want to do it in Java and have a java.sql.Date and a long:

public java.sql.Date dateAdd(java.sql.Date inputDate, long duration)
{
    return new java.sql.Date(inputDate.getTime() + duration);
}

A java.sql.Timestamp can be used in place of a java.sql.Date in either the argument or the return value, if required.
