// Summary: The clocks the PIN lockout uses, behind a class so tests can inject a fake clock.
//
// Lockout delays use the trusted clock (GPS-synced, not user-adjustable) when
// it is synced, and the system uptime timer otherwise (README 7.6). Tests
// replace this class with one whose clocks they set by hand, which makes the
// lockout schedule, restarts and clock loss testable.

    }

    // Trusted unix time in seconds, or null when the trusted clock isn't synced.
    function trustedUnix() as Long? {
        return Clock.trustedUnix();
    }

    // Milliseconds from the system timer. It restarts at zero when the watch
    // restarts and wraps after about 24.8 days.
