Struct SystemClock 

pub struct SystemClock;

Production wall-clock that reads SystemTime::now().

On system time error, returns 0 (fail-closed): a timestamp of 0 is before any real window_start, so existing windows will not expire and rate limiting continues to be enforced with existing counters. New windows started while the clock is broken will have window_start = 0; when the clock recovers, those windows will immediately expire (since any real timestamp ≥ 0 + window_secs) and reset naturally.
