Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
python-scrapy could not be built reproducibly.
This is because it uses the current build year when building the
documentation which, of course, changes depending which year you
build the software.
Patch attached that uses SOURCE_DATE_EPOCH [1] instead.
