Trait Clock 

pub trait Clock:
    Send
    + Sync
    + 'static {
    // Required method
    fn now(&self) -> Timestamp;

    // Provided methods
    fn now_in(&self, tz: &TimeZone) -> Zoned { ... }
    fn today_in(&self, tz: &TimeZone) -> Date { ... }
    fn now_unix_millis(&self) -> i64 { ... }
}

Wall-clock readouts. Single port for “what time is it?” across all surfaces.

now() is the only required method; the zone-aware readouts derive from it via jiff (tzdb available on every arm, including wasm via the bundled db).

Required Methods

fn now(&self) -> Timestamp

The current instant. The one method an arm implements.

Provided Methods

fn now_in(&self, tz: &TimeZone) -> Zoned

The current instant as a wall-clock reading in tz.

fn today_in(&self, tz: &TimeZone) -> Date

Today’s calendar date in tz — the date a person in that zone reads off their calendar, which differs from the UTC date near midnight.

fn now_unix_millis(&self) -> i64

The current instant as Unix epoch milliseconds.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
