如果为真,则 Date 标头将自动生成并在响应中发送,如果它尚未出现在标头中。 默认为真。

这应该仅在测试时禁用; HTTP 需要响应中的 Date 标头。

When true, the Date header will be automatically generated and sent in the response if it is not already present in the headers. Defaults to true.

This should only be disabled for testing; HTTP requires the Date header in responses.
