Proposed resolution:

This wording is relative to N4830.

  1. Modify the literal-char grammar in [time.format] as indicated:

    literal-char:
              any character other than {, or }, or %

The chrono-spec grammar introduced by P1361R2 "Integration of chrono with text formatting" in section [time.format] is ambiguous because '%' can be interpreted as either literal-char or conversion-spec:

chrono-spec     ::= literal-char | conversion-spec
literal-char    ::= <a character other than '{' or '}'>
conversion-spec ::= '%' [modifier] type
