Bug#900410: mtools: please make the output reproducible (directory timestamps)

[Chris Lamb]

Source: mtools
Version: 4.0.18-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that mtools generates non-reproducible output.

This is because it uses the current time of day as a default
timestamp, such as when adding files to an existing file.

Patch attached that uses SOURCE_DATE_EPOCH [1].
