pub fn notify_clock_sync(t_synced: SystemTime)Expand description
Time-source providers (PTP/NTP integrations, hardware-clock
drivers) call this when they receive a fresh sync from their
upstream master. Every registered register_clock_sync_hook
callback fires with t_synced — the time the source reports as
authoritative right now.
notify_clock_sync does NOT itself update any internal cache —
get_current and get_event keep their existing ratchet semantics
(a backward step is rejected). The hook is purely a notification
channel for downstream consumers (records that want to log a
step, archivers that want to insert a discontinuity marker).
