Dear Maintainer,

it seems that zip ignores the environment variable SOURCE_DATE_EPOCH defined by https://reproducible-builds.org/ (see https://reproducible-builds.org/specs/source-date-epoch/ and https://reproducible-builds.org/docs/source-date-epoch/ for further details).

While there are many other tools for creating reproducible zip archives, zip is ubiquitous, available on many systems, and thus used by default by many programs/scripts/...

It would be thus beneficial if zip, especially with the option -X, would ignore the file timestamps and creates a reproducible archive when SOURCE_DATE_EPOCH is defined.

This would help to make all tools that use zip internally to be a little more reproducible!
