It might be helpful to disclose to us more details about the version of
POV-Ray you're using - exact version (3.7.0 stable? A later 3.7.0
version? 3.7.1-whatever?), platform and last not least compiler used to
build it.

If the compiler version wasn't auto-detected at compile-time, it won't
be included.

There was a discussion back then about what to put in there and what not.

One result of the discussion was that all file formats that support
metadata should include the same information, which limits it to 4 lines
of 40(?) characters each.

As for the render time, there was no consensus whether to specifically
include it, or specifically exclude it.
