1. What is exact version of your server?

2. If you say that "No other change to the httpd.conf file", what
caused the difference in ETag value?

3. Overall, this is strange.
If you do an HTTP/1.1 request (using curl without "--http2" flag),
does it respond with a correct Date header?

4. I wonder, whether the behaviour is affected by H2SerializeHeaders directive.
