调度中心与执行器双向通讯超时时间调整为3s

doc/XXL-JOB官方文档.md

 任务调度错过触发时间时的处理策略：
 - 可能原因：服务重启；调度线程被阻塞，线程被耗尽；上次调度持续阻塞，下次调度被错过；
 - 处理策略：
-    - 过期超10s：本地忽略，当前时间开始计算下次触发时间
-    - 过期超过5s：过期10s内：立即触发一次，当前时间开始计算下次触发时间
+    - 过期超5s：本地忽略，当前时间开始计算下次触发时间
+    - 过期超过5s：过期5s内：立即触发一次，当前时间开始计算下次触发时间
 
 
 #### 5.4.7 日志回调服务
 - 10、项目依赖升级至较新稳定版本，如spring、springboot、groovy、xxl-rpc等等；并清理冗余POM；
 - 11、升级xxl-rpc至较新版本，修复代理服务初始化时远程服务不可用导致长连冗余创建的问题;
 - 12、首页调度报表的日期排序在TIDB下乱序问题修复；
+- 13、调度中心与执行器双向通讯超时时间调整为3s；
 
 
 ### 6.26 版本 v2.1.1 Release Notes[规划中]
