Struct der::asn1::GeneralizedTime

pub struct GeneralizedTime(_);

ASN.1 GeneralizedTime type.

This type implements the validity requirements specified in RFC 5280 Section 4.1.2.5.2, namely:

For the purposes of this profile, GeneralizedTime values MUST be expressed in Greenwich Mean Time (Zulu) and MUST include seconds (i.e., times are YYYYMMDDHHMMSSZ), even where the number of seconds is zero. GeneralizedTime values MUST NOT include fractional seconds.
