Function Documentation

date_time_period_set boost::locale::operator+	(	date_time_period_set const &	a,
		date_time_period_set const &	b
	)		[inline]

Append two periods sets. Note this operator is not commutative

date_time_period_set boost::locale::operator-	(	date_time_period_set const &	a,
		date_time_period_set const &	b
	)		[inline]

Append two period sets when all periods of set change their sign

date_time_duration boost::locale::operator-	(	date_time const &	later,
		date_time const &	earlier
	)		[inline]

Calculates the difference between two dates, the left operand is a later point on time line. Returns date_time_duration object.

template<typename CharType >

std::basic_ostream<CharType>& boost::locale::operator<<	(	std::basic_ostream< CharType > &	out,
		date_time const &	t
	)

Writes date_time t to output stream out.

This function uses locale, calendar and time zone of the target stream in.

For example:

  date_time now(time(0),hebrew_calendar)
  cout << "Year: " << period::year(now) <<" Full Date:"<< now;

The output may be Year:5770 Full Date:Jan 1, 2010

template<typename CharType >

std::basic_istream<CharType>& boost::locale::operator>>	(	std::basic_istream< CharType > &	in,
		date_time &	t
	)

Reads date_time t from output stream in

This function uses locale, calendar and time zone of the source stream in.
