尝试从Workbench的"Try Samples“中设置员工花名册，并尝试将其设置为通过REST API访问解决方案。我在使用POST上传我的数据集时遇到了一个问题，我在下面列出了我尝试和面对的详细情况。

在此之前，当我注册(PUT)我的求解器状态时，我会得到NOT_SOLVING as config.xml。这是我们将获得的实际状态吗？

分析日期格式时出错。

代码语言：javascript
复制
<startTime>2017-01-01T00:00</startTime>

并尝试了不同的格式，如下所示，但没有帮助。

代码语言：javascript
复制
 <startTime>2017-01-01 00:00</startTime>

环境详细信息：

代码语言：javascript
复制
wildfly-10.0.0.Final

Workbench(for WildFly10)

问题出在给定的日期格式上。我通过对引起问题的jars进行反编译完成了整个过程。

实际上，它期望的日期格式是：

代码语言：javascript
复制
<startTime>2017-01-01T16:00:01.001</startTime>

但我在许多例子中看到的是：

代码语言：javascript

<startTime>2017-01-01T00:00</startTime>
