Struct Clock 

pub struct Clock { /* private fields */ }

The current time — registered as a World resource.

Synced once per poll loop iteration by a clock poller. Handlers read via Res<Clock>.

Example

fn on_event(clock: Res<Clock>, event: SomeEvent) {
    let timestamp = clock.unix_nanos();
    let when = clock.instant();
}

Implementations

pub fn instant(&self) -> Instant

Monotonic instant from this poll iteration.

pub fn unix_nanos(&self) -> i128

UTC nanoseconds since Unix epoch (1970-01-01 00:00:00 UTC).
