Struct opcua_core::prelude::date_time::DateTime

source · [−]

pub struct DateTime { /* private fields */ }

Expand description

A date/time value. This is a wrapper around the chrono type with extra functionality for obtaining ticks in OPC UA measurements, endtimes, epoch etc.

Implementations

impl DateTime

pub fn now() -> DateTime

Constructs from the current time

pub fn now_with_offset(offset: Duration) -> DateTime

Constructs from the current time with an offset

pub fn null() -> DateTime

Creates a null date time (i.e. the epoch)

pub fn is_null(&self) -> bool

Tests if the date time is null (i.e. equal to epoch)

pub fn epoch() -> DateTime

Constructs a date time for the epoch

pub fn endtimes() -> DateTime

Constructs a date time for the endtimes

pub fn endtimes_ticks() -> i64

Returns the maximum tick value, corresponding to the end of time
