[Pkg-javascript-devel] Bug#1012614: node-dommatrix: please make the build reproducible

[Chris Lamb]

Source: node-dommatrix
Version: 1.0.3+dfsg-2
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
the node-dommatrix package could not be built reproducibly.

This is because it generates a "Copyright (C) ..." message based on
the current year. A patch is attached that uses the value from the
SOURCE_DATE_EPOCH environment variable instead.
