std::chrono::ambiguous_local_time
<chrono>
Defines a type of object to be thrown as exception to report that an attempt was made to convert an ambiguous std::chrono::local_time to a std::chrono::sys_time without specifying a std::chrono::choose (such as choose::earliest
or choose::latest
).
This exception is thrown by std::chrono::time_zone::to_sys and functions that call it (such as the constructors of std::chrono::zoned_time that take a std::chrono::local_time).

std::chrono::ambiguous_local_time::ambiguous_local_time
ambiguous_local_time( const std::chrono::local_time <Duration>& tp,
Constructs the exception object.
std::ostringstream os; os << tp << " is ambiguous. It could be\n" << tp << ' ' << i.first.abbrev << " == " << tp - i.first.offset << " UTC or\n" << tp << ' ' << i.second.abbrev << " == " << tp - i.second.offset << " UTC";

then std::strcmp (what(), other.what()) == 0.Parameters

Exceptions
May throw std::bad_alloc
Notes
Because copying a standard library class derived from std::exception is not permitted to throw exceptions, this message is typically stored internally as a separately-allocated reference-counted string.
std::chrono::ambiguous_locale_time::operator=
Assigns the contents with those of other. If *this and other both have dynamic type std::chrono::ambiguous_locale_time
then std::strcmp (what(), other.what()) == 0 after assignment.
Parameters
Return value
*this
std::chrono::ambiguous_locale_time::what
Returns the explanatory string.
Return value
Pointer to an implementation-defined null-terminated string with explanatory information. The string is suitable for conversion and display as a std::wstring . The pointer is guaranteed to be valid at least until the exception object from which it is obtained is destroyed, or until a non-const member function (e.g. copy assignment operator) on the exception object is called.
Notes
Implementations are allowed but not required to override what()
.
