Indeed, we've been tracking this for a while in the Reproducible Builds
project [0] but, without a patch, we did not wish to bother you with a
bug. :)
It is affecting at least 4 or 5 other packages. I had previously tracked
it down to [1].
Regarding the solution, I think I would actually prefer to see something
consuming SOURCE_DATE_EPOCH[1] rather than adding an option to set a
specific timestamp.
