This still appears to be needed... (or some other fix using
SOURCE_DATE_EPOCH, although that still arguably gives incorrect
information about the copyright headers, even if it makes it
reproducible).

... Unfortunately, there are other random factors in jmeter-apidoc that
require further exploration, possibly due to javadoc flipping between
two or three elements, creating reproducibility issues ~33-50% of the
time.


That said, fixing the date issues does appears to make jmeter-help fully
reproducible!

It would be nice to get these fixes included; I would like to perform an
NMU fixing this sometime in the next week or two, unless one of the
maintainers beats me to it. :)


live well,
