Struct der::UtcTime

pub struct UtcTime(_);

ASN.1 UTCTime type.

This type implements the validity requirements specified in RFC 5280 Section 4.1.2.5.1, namely:

For the purposes of this profile, UTCTime values MUST be expressed in Greenwich Mean Time (Zulu) and MUST include seconds (i.e., times are YYMMDDHHMMSSZ), even where the number of seconds is zero. Conforming systems MUST interpret the year field (YY) as follows:

• Where YY is greater than or equal to 50, the year SHALL be interpreted as 19YY; and
• Where YY is less than 50, the year SHALL be interpreted as 20YY.

Implementations
