- Agent 1.12.0 stamps each post with sent_at; ingest compares it with the moment the post arrived: clock_offset_s / clock_checked_at on the registration (host_agent_003), and a clock_off_secs metric (either way) that alert rules can watch. Replaces the old skew log, which measured the newest sample and was off by up to an interval. - Settings -> Thresholds: Clock drift, 30 s warn / 5 min critical. - Host page: 'clock 0.3s ahead' in the vitals line, toned past the warning. - Hosts list: names hosts whose clock is off; when every reporting host is off by about the same amount, says Steward's own clock is the likely one.
