Struct LocalTime 

pub struct LocalTime { /* private fields */ }

Shows a <time> in the browser locale and time zone.

The server writes UTC text. The browser replaces it with local text. If the element has no title, the runtime copies the server text to title. The locale is the nearest lang attribute, or the browser locale. The runtime sets the text one time, when it binds. The text does not update.

To format many <time datetime> elements, put data-vanilla=(Behavior::LocalTime) on a container.

The type uses chrono through autumn_web::reexports::chrono.

use autumn_plugin_vanilla::{LocalTime, TimeFormat};
use autumn_web::reexports::chrono::{TimeZone as _, Utc};

let at = Utc.with_ymd_and_hms(2026, 10, 5, 12, 0, 0).unwrap();
let html = LocalTime::new(&at).format(TimeFormat::Date).render().into_string();
assert!(html.starts_with(r#"<time datetime="2026-10-05T12:00:00Z""#), "{html}");

Implementations

impl LocalTime

pub fn new<Tz: TimeZone>(at: &DateTime<Tz>) -> Self

Shows at. It converts any time zone to UTC for datetime.

pub const fn format(self, format: TimeFormat) -> Self

Sets the format.

pub fn fallback(self, text: impl Into<String>) -> Self

Sets the text to show without JavaScript. The default is UTC text that matches the format, for example 2026-10-05 12:00 UTC.

pub fn attributes(&self) -> Attributes

The attributes, in render order.

pub fn render(&self) -> Markup

Renders the <time> element.

impl LocalTime

pub fn attr(self, name: &'static str, value: impl Into<String>) -> Self

Adds an extra attribute, for example id, class or aria-label.

The name must start with an ASCII letter and contain only ASCII letters, digits, -, _ and :. The builder ignores (and logs) event handler names (on…), style, type and data-vanilla… names.
