Date
addMonths(
Date const& original,
int numMonths,
bool eomFlag);Return the date that is the specified numMonths from the specified original date, adjusted as necessary according to the specified eomFlag (end-of-month flag). If eomFlag is true and original is the last day of the month, then adjust the result to be the last day of the month; if eomFlag is false, then no such adjustment is performed. In any case, if the day of the month in original does not exist in the month of the result (e.g., February 29, 2001), move the resulting date to the last day of the month. The behavior is undefined unless the operation results in a valid Date value. Note that numMonths may be negative.
