Running "./console core:purge-old-archive-data all" fails on some system with [Exception] Date format #11778
Description
Running the following command works on most servers (demo2, localhost, etc.)
./console core:purge-old-archive-data all
But on demo.piwik.org it does not work and outputs:
[Exception]
Date format must be: YYYY-MM-DD, or 'today' or 'yesterday' or any keyword supported by the strtotime function (see http://php.net/strtotime for more information): -2976912000
core:purge-old-archive-data [--exclude-outdated] [--exclude-invalidated] [--exclude-ranges] [--skip-optimize-tables] [--include-year-archives] [--force-optimize-tables] [dates1] ... [datesN]
We should investigate to make sure this command always work as we use it for time to time.
