/*
	chrono_duration.h

	Custom serializer for xsd:duration stored in a std::chrono::nanoseconds
	object.

	Requires C++11 or higher (compile with -std=c++11).

	Can represent 384307168 days (2^63 nanoseconds) forward and backward.

	Durations that exceed a month are always output in days, rather than
	months to avoid days-per-month conversion inacurracies.

	Durations that are received in years and months instead of total number
	of days from a reference point are not well defined, since there is no
	accepted reference time point (it may or may not be the current time).
	The decoder simple assumes that there are 30 days per month. For
	example, conversion of "P4M" gives 120 days. Therefore, the durations
	"P4M" and "P120D" are assumed to be identical, which is not necessarily
	true depending on the reference point in time.

	Adding std::chrono::nanoseconds values to values of
	std::chrono::system_clock::time_point is safe.

	Rescaling of the duration value by may be needed when adding the
	duration value to a `time_t` value, because `time_t` may or may not
	have a seconds resolution, depending on the platform and possible
	changes to `time_t`.

	#import this file into your gSOAP .h file

	To automate the wsdl2h-mapping of xsd:duration to
	std::chrono::nanoseconds, add this line to the typemap.dat file:

	xsd__duration = #import "custom/chrono_nanoseconds.h" | xsd__duration

	The typemap.dat file is used by wsdl2h to map types (wsdl2h option -t).

	When using soapcpp2 option -q<name> or -p<name>, you must change
	chrono_duration.cpp as follows:

		#include "soapH.h"  ->  #include "nameH.h"

	Compile and link your code with custom/chrono_duration.cpp
