示例1:
/*! Subtracts a years object and a local_date_time. Result will be same
* month and day-of-month as local_date_time unless original day was the
* last day of month. see date_time::years_duration for more details */
inline
local_date_time
operator-(const local_date_time& t, const boost::gregorian::years& y)
{
// get_neg_offset returns a negative duration, so we add
return t + y.get_neg_offset(t.utc_time().date());
}示例2:
/*! Subtracts a years object from a ptime. Result will be same
* month and day-of-month as ptime unless original day was the
* last day of month. see date_time::years_duration for more details */
inline
ptime
operator-=(ptime& t, const boost::gregorian::years& y)
{
// get_neg_offset returns a negative duration, so we add
return t += y.get_neg_offset(t.date());
