// __get_formatted_time reads input that is assumed to be formatted

// and do_get_date virtual functions, which depend on the locale
// specifications for the time and day formats respectively.
// Note the catchall default case, intended mainly for the '%Z'
// format designator, which does not make sense here since the
// representation of timezones is not part of the locale.
//
// The case branches are implemented either by doing a match using
// the appopriate name table or by doing a __get_integer_nogroup.
//
// 'y' format is assumed to mean that the input represents years
// since 1900.  That is, 2002 should be represented as 102.  There
// is no century-guessing.
//
// The match is successful if and only if the second component of the
// return value is format_end.

// Note that the antepenultimate parameter is being used only to determine
// the correct overloading for the calls to __get_integer_nogroup.
