Module clock 

Injectable clock abstraction for time-dependent risk primitives.

CircuitBreaker and SessionPnl both depend on wall-clock time — the breaker’s rolling loss window, the PnL session’s 00:00 UTC rollover. Real code uses the SystemClock; tests can substitute ManualClock (or any other Clock impl) so they don’t have to sleep for hours to exercise rollover boundaries.

use std::sync::Arc;
use rustrade_risk::clock::{Clock, ManualClock};

let clock = Arc::new(ManualClock::new(1_000));
assert_eq!(clock.now_unix_secs(), 1_000);
clock.advance_secs(86_400);
assert_eq!(clock.now_unix_secs(), 87_400);

Structs

ManualClock

A manually-advanceable clock for tests.

SystemClock

The default clock — reads the OS wall clock via SystemTime.

Traits

Clock

Source of wall-clock time, in whole UNIX seconds.
