Struct der::DateTime

source ·
pub struct DateTime { /* private fields */ }
Expand description

Date-and-time type shared by multiple ASN.1 types (e.g. GeneralizedTime, UTCTime).

Following conventions from RFC 5280, this type is always Z-normalized (i.e. represents a UTC time). However, it isn’t named “UTC time” in order to prevent confusion with ASN.1 UTCTime.

Implementations§

source§

impl DateTime

source

pub fn new( year: u16, month: u8, day: u8, hour: u8, minutes: u8, seconds: u8 ) -> Result<Self>
