With version 2.8.3 when running the command:
./console core:archive --force-all-websites --force-all-periods=315576000 --force-date-last-n=1000 --url=http://piwik.gpc.edu/piwik
I noticed the output from it is UTC, not local, although ours is set both in php and piwik as New York.
I doubled checked both the piwik web interface under Websites and the ‘php -i’ output. The core command
output had 14:04 in the afternoon when it was 9:04 in the morning.
