Bug#1117742: mobilitydb: please make the build reproducible

[Chris Lamb]

Source: mobilitydb
Version: 1.3.0~alpha-2
Severity: wishlist
Tags: patch

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
mobilitydb could not be built reproducibly.

This is because the package included a timestamp that, whilst based on
SOURCE_DATE_EPOCH, varied on the current timezone.

Patch attached that specifies UTC.
