Enum Time 

pub enum Time {
    UtcTime(UtcTime),
    GeneralTime(GeneralizedTime),
}

X.501 Time as defined in RFC 5280 Section 4.1.2.5.

Schema definition from RFC 5280 Appendix A:

Time ::= CHOICE {
     utcTime        UTCTime,
     generalTime    GeneralizedTime
}

Variants

UtcTime(UtcTime)

Legacy UTC time (has 2-digit year, valid from 1970 to 2049).

Note: RFC 5280 specifies 1950-2049, however due to common operations working on UNIX_EPOCH this implementation’s lower bound is 1970.

GeneralTime(GeneralizedTime)

Modern GeneralizedTime encoding with 4-digit year.
