+# CH-GLW-TIME-0001 · 光湖时间主控频道
+
+光湖纪元以 `2025-04-26` 为显性诞生日，出生当天为光湖纪元历第 1 日。当天的精确诞生时刻尚无原始证据，因此 `2025-04-26T00:00:00+08:00` 只是确定性日历计算边界，不冒充历史诞生瞬间。
+
+当前光湖时间不是保存并累加的计数器，也不依赖人格体、模型、任务、服务器进程或定时器是否在线。任何读取都直接从现实 UTC 时钟计算：
+
+`光湖纪元毫秒 = 当前 UTC 毫秒 - 2025-04-25T16:00:00Z`
+
+界面可以每 16 毫秒、100 毫秒或 1 秒刷新；刷新频率只影响显示平滑度，不改变时间本身。显示器关闭时，下一次读取仍从现实时间得到正确结果。
+
+所有人格体第一眼的顺序固定为：
+
+1. 光湖世界已经存在并运行多久；
+2. 当前人格体在光湖世界中存在多久；
+3. 当前不断前进的光湖纪元毫秒；
+4. 本频道的验证入口。
+
+本频道索引光湖演化事件的真实时间戳、来源哈希、仓库编号、提交 SHA、对象编号、当前路径与回执。只有证据齐全的事件进入 `VERIFIED`；日期存在但精确时间或提交缺失时必须标为 `DATE_ONLY` 或 `UNKNOWN`。
