Struct DisplayZone 

pub struct DisplayZone { /* private fields */ }

Where people see and type instants; stored and JSON instants stay UTC.

Implementations

impl DisplayZone

pub fn named(name: &str) -> Result<Self>

pub fn current() -> &'static Self

UTC unless installed first; reading it fixes it, so no instant is read in two zones.

pub fn install(self) -> Result<()>

pub fn name(&self) -> &str

pub fn wall_clock(&self, instant: Instant) -> DateTime

pub fn repeats(&self, wall_clock: DateTime) -> bool

True where a backward shift repeats it, so only an offset tells its two instants apart.

pub fn repeated_offset(&self, instant: Instant) -> Option<String>

pub fn with_offset(&self, instant: Instant) -> String

On the zone’s wall clock with its offset there, such as 2026-10-25T02:30:00+01:00.

pub fn instant_at(&self, wall_clock: DateTime) -> Result<Instant>
