当输入是 nextLong() 可接受、但绝对值超过毫秒换算范围的秒值时（例如 9223372036854776），这里的乘法会发生 long 溢出并静默生成完全错误的 Date；旧实现会因超出 int 范围而拒绝该输入。请在乘法前校验边界或使用 Math.multiplyExact 并将溢出转换为解析异常，避免异常响应被当作有效日期。

weixin-java-common/pom.xml 将 Surefire 固定配置为运行 src/test/resources/testng.xml，而该 suite 只显式列出了原有的六个测试类，没有包含 WxDateTypeAdapterTest；因此 CI 的 mvn clean test -Dmaven.test.skip=false 不会执行这里新增的五个测试，日期溢出回归也不会被门禁发现。请把该类加入 suite，或调整配置以启用测试类自动发现。

🟡 Changes recommended
The new regression test must be added to the configured TestNG suite before approval.

Pull request overview
修复 WxDateTypeAdapter 解析秒级时间戳时的 int 溢出问题，并新增回归测试。
Changes:
- 使用
long读取并转换时间戳。 - 增加 2038 年后时间戳、空值及序列化测试。
- 中等问题：新增测试尚未加入固定 TestNG suite，Maven 当前不会执行该测试。
