+ * 时辰转换器，支持宋以后的二十四时辰制度。
+ * <p>本转换器提供以下功能：
+ * <ul>
+ * <li>处理包含“时”、“初”或“正”后缀的长安时辰描述，并自动返回相应的现代时间段。
+ * “初”和“正”分别对应每个时辰的前半段和后半段，而不带后缀的“时”描述则涵盖该时辰的完整时间段。</li>
+ * <li>根据小时数转换为相应的长安时辰描述，通过{@code isAbs}参数控制是否包含“初”或“正”。</li>
+ * </ul>
+ * </p>
+ * <p>
+ * 异常情况：
+ * <ul>
+ * <li>如果输入的长安时辰描述无效或不被识别，{@code toModernTime} 方法将抛出 {@code IllegalArgumentException}。</li>
+ * <li>同样，如果{@code toShiChen}方法接收到无效的小时数，将返回“未知”。</li>
+ * </ul>
+ * </p>
+ * <p>
+ * 示例：
+ * <ul>
+ * <li>{@code toModernTime("子时")} 返回的时间段从23点开始到1点结束。</li>
+ * <li>{@code toModernTime("子初")} 返回的时间段从23点开始到0点结束。</li>
+ * <li>{@code toModernTime("子正")} 返回的时间段从0点开始到1点结束。</li>
