Description

English:
Time synchronization notification. Reported when the device time synchronization state changes, including synchronization source switch, offset exceeding the threshold and Network Time Protocol (NTP) service abnormality.
Recommended severity: major. Recommended handling: check the NTP server address, network reachability and system time; time skew causes certificate validation failure, log correlation error and audit evidence invalidation, and also breaks CRL and OCSP freshness checking.
Status: registered but unused. Not yet emitted by any product; when implemented, carry the offset value, threshold and the synchronization source identifier. The unused state shall be re-verified at each revision of this file.
Recommendation: treat a time offset exceeding the certificate validity tolerance as a PKI incident and handle it together with 1.3.6.1.4.1.59719.0.3.90 (certificate chain invalid) and 1.3.6.1.4.1.59719.6.1.1 (PKI global status scalars).
See also: 1.3.6.1.4.1.59719.0.3.90, 1.3.6.1.4.1.59719.6.3.
Verification: 2026-10-22 — this arc and all its sub-ordinates are confirmed unused; re-verify the unused state at each revision of this file.

中文:
时间同步通知。设备时间同步状态变化时上报，包括同步源切换、时间偏移超阈值、网络时间协议（Network Time Protocol，NTP）服务异常。
建议级别：重要。处理建议：检查 NTP 服务器地址、网络可达性与系统时间；时间偏差会导致证书校验失败、日志关联错乱、审计取证失效，并破坏 CRL 与 OCSP 新鲜度校验。
状态：已注册但未使用。尚无产品上报该通知；实现时应携带偏移值、阈值与同步源标识。本文件每次修订时须重新核验该未使用状态。
建议：将超出证书有效期容限的时间偏移视为 PKI 事件，与 1.3.6.1.4.1.59719.0.3.90（证书链校验失败）、1.3.6.1.4.1.59719.6.1.1（PKI 全局状态标量）协同处置。
关联节点：1.3.6.1.4.1.59719.0.3.90、1.3.6.1.4.1.59719.6.3。
核验：2026-10-22 —— 本弧及其全部下级标识均确认未使用，本文件每次修订时须重新核验该未使用状态。
