When the "time/large-dates" feature is enabled, the format_description strings used to parse ASN.1 GeneralizedTime and ASN1.UTCTime becomes ambiguous. The parser will greedily consume the month digits for the leading year.

Arguably a deficiency in the upstream time crate, not seemingly allowing anyway to specify how many digits are expected in a year.
